Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707842, here are decompositions:
- 5 + 8707837 = 8707842
- 61 + 8707781 = 8707842
- 79 + 8707763 = 8707842
- 89 + 8707753 = 8707842
- 131 + 8707711 = 8707842
- 173 + 8707669 = 8707842
- 181 + 8707661 = 8707842
- 191 + 8707651 = 8707842
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,707,842 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8707842 first appears in π at position 880,752 of the decimal expansion (the 880,752ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
