Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532984, here are decompositions:
- 3 + 31532981 = 31532984
- 13 + 31532971 = 31532984
- 61 + 31532923 = 31532984
- 103 + 31532881 = 31532984
- 151 + 31532833 = 31532984
- 331 + 31532653 = 31532984
- 397 + 31532587 = 31532984
- 433 + 31532551 = 31532984
Showing the first eight; more decompositions exist.
