Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539924, here are decompositions:
- 23 + 31539901 = 31539924
- 61 + 31539863 = 31539924
- 67 + 31539857 = 31539924
- 103 + 31539821 = 31539924
- 107 + 31539817 = 31539924
- 167 + 31539757 = 31539924
- 197 + 31539727 = 31539924
- 211 + 31539713 = 31539924
Showing the first eight; more decompositions exist.
