Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484976, here are decompositions:
- 73 + 31484903 = 31484976
- 113 + 31484863 = 31484976
- 137 + 31484839 = 31484976
- 139 + 31484837 = 31484976
- 179 + 31484797 = 31484976
- 199 + 31484777 = 31484976
- 223 + 31484753 = 31484976
- 277 + 31484699 = 31484976
Showing the first eight; more decompositions exist.
