Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988142, here are decompositions:
- 13 + 988129 = 988142
- 31 + 988111 = 988142
- 73 + 988069 = 988142
- 109 + 988033 = 988142
- 151 + 987991 = 988142
- 163 + 987979 = 988142
- 229 + 987913 = 988142
- 349 + 987793 = 988142
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 988,142 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 988142 first appears in π at position 195,866 of the decimal expansion (the 195,866ordinal-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.
