Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543908, here are decompositions:
- 5 + 31543903 = 31543908
- 31 + 31543877 = 31543908
- 37 + 31543871 = 31543908
- 61 + 31543847 = 31543908
- 79 + 31543829 = 31543908
- 131 + 31543777 = 31543908
- 139 + 31543769 = 31543908
- 157 + 31543751 = 31543908
Showing the first eight; more decompositions exist.
