Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101642, here are decompositions:
- 31 + 101611 = 101642
- 43 + 101599 = 101642
- 61 + 101581 = 101642
- 109 + 101533 = 101642
- 139 + 101503 = 101642
- 193 + 101449 = 101642
- 223 + 101419 = 101642
- 283 + 101359 = 101642
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 101,642 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 101642 first appears in π at position 306,918 of the decimal expansion (the 306,918ordinal-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.
