Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052640, here are decompositions:
- 11 + 1052629 = 1052640
- 31 + 1052609 = 1052640
- 67 + 1052573 = 1052640
- 73 + 1052567 = 1052640
- 79 + 1052561 = 1052640
- 89 + 1052551 = 1052640
- 103 + 1052537 = 1052640
- 107 + 1052533 = 1052640
Showing the first eight; more decompositions exist.
