Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536156, here are decompositions:
- 59 + 31536097 = 31536156
- 103 + 31536053 = 31536156
- 107 + 31536049 = 31536156
- 137 + 31536019 = 31536156
- 139 + 31536017 = 31536156
- 173 + 31535983 = 31536156
- 277 + 31535879 = 31536156
- 347 + 31535809 = 31536156
Showing the first eight; more decompositions exist.
