Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51180, here are decompositions:
- 11 + 51169 = 51180
- 23 + 51157 = 51180
- 29 + 51151 = 51180
- 43 + 51137 = 51180
- 47 + 51133 = 51180
- 71 + 51109 = 51180
- 109 + 51071 = 51180
- 137 + 51043 = 51180
Showing the first eight; more decompositions exist.
