Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564768, here are decompositions:
- 29 + 31564739 = 31564768
- 47 + 31564721 = 31564768
- 107 + 31564661 = 31564768
- 251 + 31564517 = 31564768
- 821 + 31563947 = 31564768
- 827 + 31563941 = 31564768
- 839 + 31563929 = 31564768
- 857 + 31563911 = 31564768
Showing the first eight; more decompositions exist.
