Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425704, here are decompositions:
- 23 + 2147425681 = 2147425704
- 41 + 2147425663 = 2147425704
- 97 + 2147425607 = 2147425704
- 113 + 2147425591 = 2147425704
- 163 + 2147425541 = 2147425704
- 173 + 2147425531 = 2147425704
- 191 + 2147425513 = 2147425704
- 197 + 2147425507 = 2147425704
Showing the first eight; more decompositions exist.
