Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425488, here are decompositions:
- 31 + 2147425457 = 2147425488
- 41 + 2147425447 = 2147425488
- 107 + 2147425381 = 2147425488
- 139 + 2147425349 = 2147425488
- 179 + 2147425309 = 2147425488
- 191 + 2147425297 = 2147425488
- 239 + 2147425249 = 2147425488
- 251 + 2147425237 = 2147425488
Showing the first eight; more decompositions exist.
