Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51192, here are decompositions:
- 23 + 51169 = 51192
- 41 + 51151 = 51192
- 59 + 51133 = 51192
- 61 + 51131 = 51192
- 83 + 51109 = 51192
- 131 + 51061 = 51192
- 149 + 51043 = 51192
- 191 + 51001 = 51192
Showing the first eight; more decompositions exist.
