Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142150, here are decompositions:
- 53 + 142097 = 142150
- 83 + 142067 = 142150
- 89 + 142061 = 142150
- 101 + 142049 = 142150
- 131 + 142019 = 142150
- 179 + 141971 = 142150
- 191 + 141959 = 142150
- 233 + 141917 = 142150
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 142,150 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142150 first appears in π at position 3,096 of the decimal expansion (the 3,096ordinal-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.
