Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425608, here are decompositions:
- 17 + 2147425591 = 2147425608
- 67 + 2147425541 = 2147425608
- 89 + 2147425519 = 2147425608
- 101 + 2147425507 = 2147425608
- 151 + 2147425457 = 2147425608
- 197 + 2147425411 = 2147425608
- 227 + 2147425381 = 2147425608
- 311 + 2147425297 = 2147425608
Showing the first eight; more decompositions exist.
