Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535406, here are decompositions:
- 29 + 31535377 = 31535406
- 79 + 31535327 = 31535406
- 173 + 31535233 = 31535406
- 179 + 31535227 = 31535406
- 193 + 31535213 = 31535406
- 223 + 31535183 = 31535406
- 233 + 31535173 = 31535406
- 263 + 31535143 = 31535406
Showing the first eight; more decompositions exist.
