Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101842, here are decompositions:
- 3 + 101839 = 101842
- 5 + 101837 = 101842
- 53 + 101789 = 101842
- 71 + 101771 = 101842
- 101 + 101741 = 101842
- 149 + 101693 = 101842
- 179 + 101663 = 101842
- 239 + 101603 = 101842
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 101,842 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 101842 first appears in π at position 490,366 of the decimal expansion (the 490,366ordinal-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.
