Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545044, here are decompositions:
- 43 + 31545001 = 31545044
- 103 + 31544941 = 31545044
- 331 + 31544713 = 31545044
- 457 + 31544587 = 31545044
- 673 + 31544371 = 31545044
- 733 + 31544311 = 31545044
- 823 + 31544221 = 31545044
- 877 + 31544167 = 31545044
Showing the first eight; more decompositions exist.
