Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425788, here are decompositions:
- 29 + 2147425759 = 2147425788
- 59 + 2147425729 = 2147425788
- 107 + 2147425681 = 2147425788
- 181 + 2147425607 = 2147425788
- 197 + 2147425591 = 2147425788
- 229 + 2147425559 = 2147425788
- 257 + 2147425531 = 2147425788
- 269 + 2147425519 = 2147425788
Showing the first eight; more decompositions exist.
