Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65490, here are decompositions:
- 11 + 65479 = 65490
- 41 + 65449 = 65490
- 43 + 65447 = 65490
- 53 + 65437 = 65490
- 67 + 65423 = 65490
- 71 + 65419 = 65490
- 83 + 65407 = 65490
- 97 + 65393 = 65490
Showing the first eight; more decompositions exist.
