Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25118, here are decompositions:
- 7 + 25111 = 25118
- 31 + 25087 = 25118
- 61 + 25057 = 25118
- 139 + 24979 = 25118
- 151 + 24967 = 25118
- 199 + 24919 = 25118
- 211 + 24907 = 25118
- 229 + 24889 = 25118
Showing the first eight; more decompositions exist.
