Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545938, here are decompositions:
- 19 + 31545919 = 31545938
- 37 + 31545901 = 31545938
- 79 + 31545859 = 31545938
- 97 + 31545841 = 31545938
- 199 + 31545739 = 31545938
- 271 + 31545667 = 31545938
- 331 + 31545607 = 31545938
- 439 + 31545499 = 31545938
Showing the first eight; more decompositions exist.
