Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25212, here are decompositions:
- 23 + 25189 = 25212
- 29 + 25183 = 25212
- 41 + 25171 = 25212
- 43 + 25169 = 25212
- 59 + 25153 = 25212
- 101 + 25111 = 25212
- 139 + 25073 = 25212
- 179 + 25033 = 25212
Showing the first eight; more decompositions exist.
