Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139226, here are decompositions:
- 103 + 139123 = 139226
- 193 + 139033 = 139226
- 337 + 138889 = 139226
- 397 + 138829 = 139226
- 433 + 138793 = 139226
- 463 + 138763 = 139226
- 487 + 138739 = 139226
- 499 + 138727 = 139226
Showing the first eight; more decompositions exist.
