Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425460, here are decompositions:
- 3 + 2147425457 = 2147425460
- 7 + 2147425453 = 2147425460
- 13 + 2147425447 = 2147425460
- 67 + 2147425393 = 2147425460
- 79 + 2147425381 = 2147425460
- 127 + 2147425333 = 2147425460
- 151 + 2147425309 = 2147425460
- 163 + 2147425297 = 2147425460
Showing the first eight; more decompositions exist.
