Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12590, here are decompositions:
- 7 + 12583 = 12590
- 13 + 12577 = 12590
- 37 + 12553 = 12590
- 43 + 12547 = 12590
- 73 + 12517 = 12590
- 79 + 12511 = 12590
- 103 + 12487 = 12590
- 139 + 12451 = 12590
Showing the first eight; more decompositions exist.
