Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012518, here are decompositions:
- 5 + 1012513 = 1012518
- 11 + 1012507 = 1012518
- 29 + 1012489 = 1012518
- 37 + 1012481 = 1012518
- 61 + 1012457 = 1012518
- 71 + 1012447 = 1012518
- 79 + 1012439 = 1012518
- 97 + 1012421 = 1012518
Showing the first eight; more decompositions exist.
