Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51490, here are decompositions:
- 3 + 51487 = 51490
- 11 + 51479 = 51490
- 17 + 51473 = 51490
- 29 + 51461 = 51490
- 41 + 51449 = 51490
- 53 + 51437 = 51490
- 59 + 51431 = 51490
- 71 + 51419 = 51490
Showing the first eight; more decompositions exist.
