Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425426, here are decompositions:
- 239 + 2147425187 = 2147425426
- 257 + 2147425169 = 2147425426
- 353 + 2147425073 = 2147425426
- 359 + 2147425067 = 2147425426
- 557 + 2147424869 = 2147425426
- 563 + 2147424863 = 2147425426
- 599 + 2147424827 = 2147425426
- 617 + 2147424809 = 2147425426
Showing the first eight; more decompositions exist.
