Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25220, here are decompositions:
- 31 + 25189 = 25220
- 37 + 25183 = 25220
- 67 + 25153 = 25220
- 73 + 25147 = 25220
- 103 + 25117 = 25220
- 109 + 25111 = 25220
- 163 + 25057 = 25220
- 241 + 24979 = 25220
Showing the first eight; more decompositions exist.
