Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545170, here are decompositions:
- 73 + 31545097 = 31545170
- 79 + 31545091 = 31545170
- 103 + 31545067 = 31545170
- 109 + 31545061 = 31545170
- 229 + 31544941 = 31545170
- 271 + 31544899 = 31545170
- 313 + 31544857 = 31545170
- 421 + 31544749 = 31545170
Showing the first eight; more decompositions exist.
