Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61268, here are decompositions:
- 7 + 61261 = 61268
- 37 + 61231 = 61268
- 127 + 61141 = 61268
- 139 + 61129 = 61268
- 211 + 61057 = 61268
- 241 + 61027 = 61268
- 307 + 60961 = 61268
- 331 + 60937 = 61268
Showing the first eight; more decompositions exist.
