Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545944, here are decompositions:
- 43 + 31545901 = 31545944
- 103 + 31545841 = 31545944
- 181 + 31545763 = 31545944
- 277 + 31545667 = 31545944
- 337 + 31545607 = 31545944
- 457 + 31545487 = 31545944
- 571 + 31545373 = 31545944
- 601 + 31545343 = 31545944
Showing the first eight; more decompositions exist.
