Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015512, here are decompositions:
- 5 + 1015507 = 1015512
- 11 + 1015501 = 1015512
- 13 + 1015499 = 1015512
- 31 + 1015481 = 1015512
- 41 + 1015471 = 1015512
- 53 + 1015459 = 1015512
- 59 + 1015453 = 1015512
- 61 + 1015451 = 1015512
Showing the first eight; more decompositions exist.
