Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535510, here are decompositions:
- 7 + 31535503 = 31535510
- 43 + 31535467 = 31535510
- 199 + 31535311 = 31535510
- 277 + 31535233 = 31535510
- 283 + 31535227 = 31535510
- 337 + 31535173 = 31535510
- 367 + 31535143 = 31535510
- 379 + 31535131 = 31535510
Showing the first eight; more decompositions exist.
