Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51356, here are decompositions:
- 7 + 51349 = 51356
- 13 + 51343 = 51356
- 73 + 51283 = 51356
- 127 + 51229 = 51356
- 139 + 51217 = 51356
- 157 + 51199 = 51356
- 163 + 51193 = 51356
- 199 + 51157 = 51356
Showing the first eight; more decompositions exist.
