Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138014, here are decompositions:
- 7 + 138007 = 138014
- 31 + 137983 = 138014
- 67 + 137947 = 138014
- 73 + 137941 = 138014
- 103 + 137911 = 138014
- 211 + 137803 = 138014
- 223 + 137791 = 138014
- 271 + 137743 = 138014
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 138,014 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
