Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51236, here are decompositions:
- 7 + 51229 = 51236
- 19 + 51217 = 51236
- 37 + 51199 = 51236
- 43 + 51193 = 51236
- 67 + 51169 = 51236
- 79 + 51157 = 51236
- 103 + 51133 = 51236
- 127 + 51109 = 51236
Showing the first eight; more decompositions exist.
