Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142236, here are decompositions:
- 5 + 142231 = 142236
- 13 + 142223 = 142236
- 19 + 142217 = 142236
- 43 + 142193 = 142236
- 47 + 142189 = 142236
- 53 + 142183 = 142236
- 67 + 142169 = 142236
- 79 + 142157 = 142236
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 142,236 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 142236 first appears in π at position 754,702 of the decimal expansion (the 754,702ordinal-suffix:nd 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.
