Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545624, here are decompositions:
- 13 + 31545611 = 31545624
- 17 + 31545607 = 31545624
- 137 + 31545487 = 31545624
- 223 + 31545401 = 31545624
- 233 + 31545391 = 31545624
- 251 + 31545373 = 31545624
- 281 + 31545343 = 31545624
- 293 + 31545331 = 31545624
Showing the first eight; more decompositions exist.
