Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535304, here are decompositions:
- 41 + 31535263 = 31535304
- 71 + 31535233 = 31535304
- 131 + 31535173 = 31535304
- 173 + 31535131 = 31535304
- 181 + 31535123 = 31535304
- 191 + 31535113 = 31535304
- 197 + 31535107 = 31535304
- 223 + 31535081 = 31535304
Showing the first eight; more decompositions exist.
