Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51278, here are decompositions:
- 37 + 51241 = 51278
- 61 + 51217 = 51278
- 79 + 51199 = 51278
- 109 + 51169 = 51278
- 127 + 51151 = 51278
- 277 + 51001 = 51278
- 307 + 50971 = 51278
- 349 + 50929 = 51278
Showing the first eight; more decompositions exist.
