Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51492, here are decompositions:
- 5 + 51487 = 51492
- 11 + 51481 = 51492
- 13 + 51479 = 51492
- 19 + 51473 = 51492
- 31 + 51461 = 51492
- 43 + 51449 = 51492
- 53 + 51439 = 51492
- 61 + 51431 = 51492
Showing the first eight; more decompositions exist.
