Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51246, here are decompositions:
- 5 + 51241 = 51246
- 7 + 51239 = 51246
- 17 + 51229 = 51246
- 29 + 51217 = 51246
- 43 + 51203 = 51246
- 47 + 51199 = 51246
- 53 + 51193 = 51246
- 89 + 51157 = 51246
Showing the first eight; more decompositions exist.
