Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426958, here are decompositions:
- 7 + 2147426951 = 2147426958
- 137 + 2147426821 = 2147426958
- 211 + 2147426747 = 2147426958
- 277 + 2147426681 = 2147426958
- 307 + 2147426651 = 2147426958
- 317 + 2147426641 = 2147426958
- 401 + 2147426557 = 2147426958
- 431 + 2147426527 = 2147426958
Showing the first eight; more decompositions exist.
