Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51624, here are decompositions:
- 11 + 51613 = 51624
- 17 + 51607 = 51624
- 31 + 51593 = 51624
- 43 + 51581 = 51624
- 47 + 51577 = 51624
- 61 + 51563 = 51624
- 73 + 51551 = 51624
- 103 + 51521 = 51624
Showing the first eight; more decompositions exist.
