Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100542, here are decompositions:
- 5 + 100537 = 100542
- 19 + 100523 = 100542
- 23 + 100519 = 100542
- 31 + 100511 = 100542
- 41 + 100501 = 100542
- 59 + 100483 = 100542
- 73 + 100469 = 100542
- 83 + 100459 = 100542
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 100,542 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 100542 first appears in π at position 498,116 of the decimal expansion (the 498,116ordinal-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.
