Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51540, here are decompositions:
- 19 + 51521 = 51540
- 23 + 51517 = 51540
- 29 + 51511 = 51540
- 37 + 51503 = 51540
- 53 + 51487 = 51540
- 59 + 51481 = 51540
- 61 + 51479 = 51540
- 67 + 51473 = 51540
Showing the first eight; more decompositions exist.
