Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453250, here are decompositions:
- 43 + 31453207 = 31453250
- 79 + 31453171 = 31453250
- 109 + 31453141 = 31453250
- 211 + 31453039 = 31453250
- 229 + 31453021 = 31453250
- 277 + 31452973 = 31453250
- 307 + 31452943 = 31453250
- 349 + 31452901 = 31453250
Showing the first eight; more decompositions exist.
