Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51718, here are decompositions:
- 5 + 51713 = 51718
- 59 + 51659 = 51718
- 71 + 51647 = 51718
- 137 + 51581 = 51718
- 167 + 51551 = 51718
- 179 + 51539 = 51718
- 197 + 51521 = 51718
- 239 + 51479 = 51718
Showing the first eight; more decompositions exist.
