Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51272, here are decompositions:
- 31 + 51241 = 51272
- 43 + 51229 = 51272
- 73 + 51199 = 51272
- 79 + 51193 = 51272
- 103 + 51169 = 51272
- 139 + 51133 = 51272
- 163 + 51109 = 51272
- 211 + 51061 = 51272
Showing the first eight; more decompositions exist.
