Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448256, here are decompositions:
- 23 + 31448233 = 31448256
- 107 + 31448149 = 31448256
- 199 + 31448057 = 31448256
- 223 + 31448033 = 31448256
- 233 + 31448023 = 31448256
- 239 + 31448017 = 31448256
- 269 + 31447987 = 31448256
- 293 + 31447963 = 31448256
Showing the first eight; more decompositions exist.
