Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047480, here are decompositions:
- 11 + 1047469 = 1047480
- 13 + 1047467 = 1047480
- 61 + 1047419 = 1047480
- 89 + 1047391 = 1047480
- 101 + 1047379 = 1047480
- 107 + 1047373 = 1047480
- 113 + 1047367 = 1047480
- 139 + 1047341 = 1047480
Showing the first eight; more decompositions exist.
