Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484040, here are decompositions:
- 59 + 31483981 = 31484040
- 61 + 31483979 = 31484040
- 83 + 31483957 = 31484040
- 113 + 31483927 = 31484040
- 127 + 31483913 = 31484040
- 151 + 31483889 = 31484040
- 157 + 31483883 = 31484040
- 163 + 31483877 = 31484040
Showing the first eight; more decompositions exist.
