Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543896, here are decompositions:
- 19 + 31543877 = 31543896
- 23 + 31543873 = 31543896
- 37 + 31543859 = 31543896
- 53 + 31543843 = 31543896
- 67 + 31543829 = 31543896
- 79 + 31543817 = 31543896
- 113 + 31543783 = 31543896
- 127 + 31543769 = 31543896
Showing the first eight; more decompositions exist.
