Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142964, here are decompositions:
- 61 + 142903 = 142964
- 67 + 142897 = 142964
- 97 + 142867 = 142964
- 127 + 142837 = 142964
- 193 + 142771 = 142964
- 307 + 142657 = 142964
- 373 + 142591 = 142964
- 397 + 142567 = 142964
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 142,964 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
