Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545038, here are decompositions:
- 37 + 31545001 = 31545038
- 97 + 31544941 = 31545038
- 139 + 31544899 = 31545038
- 181 + 31544857 = 31545038
- 211 + 31544827 = 31545038
- 487 + 31544551 = 31545038
- 691 + 31544347 = 31545038
- 727 + 31544311 = 31545038
Showing the first eight; more decompositions exist.
