Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448370, here are decompositions:
- 47 + 31448323 = 31448370
- 61 + 31448309 = 31448370
- 67 + 31448303 = 31448370
- 71 + 31448299 = 31448370
- 73 + 31448297 = 31448370
- 89 + 31448281 = 31448370
- 137 + 31448233 = 31448370
- 179 + 31448191 = 31448370
Showing the first eight; more decompositions exist.
