Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536168, here are decompositions:
- 7 + 31536161 = 31536168
- 67 + 31536101 = 31536168
- 71 + 31536097 = 31536168
- 107 + 31536061 = 31536168
- 149 + 31536019 = 31536168
- 151 + 31536017 = 31536168
- 227 + 31535941 = 31536168
- 229 + 31535939 = 31536168
Showing the first eight; more decompositions exist.
