Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448928, here are decompositions:
- 19 + 31448909 = 31448928
- 29 + 31448899 = 31448928
- 31 + 31448897 = 31448928
- 37 + 31448891 = 31448928
- 89 + 31448839 = 31448928
- 107 + 31448821 = 31448928
- 211 + 31448717 = 31448928
- 229 + 31448699 = 31448928
Showing the first eight; more decompositions exist.
