Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482864, here are decompositions:
- 5 + 31482859 = 31482864
- 31 + 31482833 = 31482864
- 41 + 31482823 = 31482864
- 43 + 31482821 = 31482864
- 103 + 31482761 = 31482864
- 157 + 31482707 = 31482864
- 181 + 31482683 = 31482864
- 197 + 31482667 = 31482864
Showing the first eight; more decompositions exist.
