Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167912, here are decompositions:
- 13 + 167899 = 167912
- 103 + 167809 = 167912
- 229 + 167683 = 167912
- 271 + 167641 = 167912
- 421 + 167491 = 167912
- 463 + 167449 = 167912
- 499 + 167413 = 167912
- 571 + 167341 = 167912
Showing the first eight; more decompositions exist.
