Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51518, here are decompositions:
- 7 + 51511 = 51518
- 31 + 51487 = 51518
- 37 + 51481 = 51518
- 79 + 51439 = 51518
- 97 + 51421 = 51518
- 157 + 51361 = 51518
- 211 + 51307 = 51518
- 277 + 51241 = 51518
Showing the first eight; more decompositions exist.
