Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425532, here are decompositions:
- 13 + 2147425519 = 2147425532
- 19 + 2147425513 = 2147425532
- 79 + 2147425453 = 2147425532
- 139 + 2147425393 = 2147425532
- 151 + 2147425381 = 2147425532
- 199 + 2147425333 = 2147425532
- 223 + 2147425309 = 2147425532
- 283 + 2147425249 = 2147425532
Showing the first eight; more decompositions exist.
