Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425822, here are decompositions:
- 263 + 2147425559 = 2147425822
- 281 + 2147425541 = 2147425822
- 653 + 2147425169 = 2147425822
- 683 + 2147425139 = 2147425822
- 701 + 2147425121 = 2147425822
- 719 + 2147425103 = 2147425822
- 821 + 2147425001 = 2147425822
- 929 + 2147424893 = 2147425822
Showing the first eight; more decompositions exist.
