Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535504, here are decompositions:
- 37 + 31535467 = 31535504
- 127 + 31535377 = 31535504
- 163 + 31535341 = 31535504
- 193 + 31535311 = 31535504
- 241 + 31535263 = 31535504
- 271 + 31535233 = 31535504
- 277 + 31535227 = 31535504
- 331 + 31535173 = 31535504
Showing the first eight; more decompositions exist.
