Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707672, here are decompositions:
- 3 + 8707669 = 8707672
- 11 + 8707661 = 8707672
- 23 + 8707649 = 8707672
- 41 + 8707631 = 8707672
- 251 + 8707421 = 8707672
- 293 + 8707379 = 8707672
- 383 + 8707289 = 8707672
- 431 + 8707241 = 8707672
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 8,707,672 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 8707672 first appears in π at position 735,629 of the decimal expansion (the 735,629ordinal-suffix:th 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.
