Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143136, here are decompositions:
- 23 + 143113 = 143136
- 29 + 143107 = 143136
- 43 + 143093 = 143136
- 73 + 143063 = 143136
- 83 + 143053 = 143136
- 157 + 142979 = 143136
- 163 + 142973 = 143136
- 167 + 142969 = 143136
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 143,136 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 143136 first appears in π at position 398,027 of the decimal expansion (the 398,027ordinal-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.
