Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425256, here are decompositions:
- 7 + 2147425249 = 2147425256
- 13 + 2147425243 = 2147425256
- 19 + 2147425237 = 2147425256
- 43 + 2147425213 = 2147425256
- 307 + 2147424949 = 2147425256
- 439 + 2147424817 = 2147425256
- 463 + 2147424793 = 2147425256
- 547 + 2147424709 = 2147425256
Showing the first eight; more decompositions exist.
