Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040520, here are decompositions:
- 17 + 1040503 = 1040520
- 31 + 1040489 = 1040520
- 37 + 1040483 = 1040520
- 71 + 1040449 = 1040520
- 73 + 1040447 = 1040520
- 101 + 1040419 = 1040520
- 109 + 1040411 = 1040520
- 113 + 1040407 = 1040520
Showing the first eight; more decompositions exist.
