Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1046640, here are decompositions:
- 13 + 1046627 = 1046640
- 41 + 1046599 = 1046640
- 43 + 1046597 = 1046640
- 53 + 1046587 = 1046640
- 61 + 1046579 = 1046640
- 83 + 1046557 = 1046640
- 113 + 1046527 = 1046640
- 181 + 1046459 = 1046640
Showing the first eight; more decompositions exist.
