Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425506, here are decompositions:
- 53 + 2147425453 = 2147425506
- 59 + 2147425447 = 2147425506
- 113 + 2147425393 = 2147425506
- 157 + 2147425349 = 2147425506
- 173 + 2147425333 = 2147425506
- 197 + 2147425309 = 2147425506
- 223 + 2147425283 = 2147425506
- 257 + 2147425249 = 2147425506
Showing the first eight; more decompositions exist.
