Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51586, here are decompositions:
- 5 + 51581 = 51586
- 23 + 51563 = 51586
- 47 + 51539 = 51586
- 83 + 51503 = 51586
- 107 + 51479 = 51586
- 113 + 51473 = 51586
- 137 + 51449 = 51586
- 149 + 51437 = 51586
Showing the first eight; more decompositions exist.
