Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718528, here are decompositions:
- 37 + 8718491 = 8718528
- 41 + 8718487 = 8718528
- 59 + 8718469 = 8718528
- 67 + 8718461 = 8718528
- 89 + 8718439 = 8718528
- 97 + 8718431 = 8718528
- 101 + 8718427 = 8718528
- 109 + 8718419 = 8718528
Showing the first eight; more decompositions exist.
