Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142070, here are decompositions:
- 3 + 142067 = 142070
- 13 + 142057 = 142070
- 31 + 142039 = 142070
- 79 + 141991 = 142070
- 109 + 141961 = 142070
- 139 + 141931 = 142070
- 163 + 141907 = 142070
- 199 + 141871 = 142070
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 142,070 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
