Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543884, here are decompositions:
- 7 + 31543877 = 31543884
- 11 + 31543873 = 31543884
- 13 + 31543871 = 31543884
- 37 + 31543847 = 31543884
- 41 + 31543843 = 31543884
- 67 + 31543817 = 31543884
- 101 + 31543783 = 31543884
- 107 + 31543777 = 31543884
Showing the first eight; more decompositions exist.
