Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671542, here are decompositions:
- 23 + 8671519 = 8671542
- 31 + 8671511 = 8671542
- 41 + 8671501 = 8671542
- 43 + 8671499 = 8671542
- 71 + 8671471 = 8671542
- 73 + 8671469 = 8671542
- 79 + 8671463 = 8671542
- 101 + 8671441 = 8671542
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 8,671,542 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 8671542 first appears in π at position 666,763 of the decimal expansion (the 666,763ordinal-suffix:rd 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.
