Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543902, here are decompositions:
- 29 + 31543873 = 31543902
- 31 + 31543871 = 31543902
- 43 + 31543859 = 31543902
- 59 + 31543843 = 31543902
- 73 + 31543829 = 31543902
- 139 + 31543763 = 31543902
- 151 + 31543751 = 31543902
- 179 + 31543723 = 31543902
Showing the first eight; more decompositions exist.
