Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425628, here are decompositions:
- 37 + 2147425591 = 2147425628
- 97 + 2147425531 = 2147425628
- 109 + 2147425519 = 2147425628
- 181 + 2147425447 = 2147425628
- 331 + 2147425297 = 2147425628
- 379 + 2147425249 = 2147425628
- 811 + 2147424817 = 2147425628
- 919 + 2147424709 = 2147425628
Showing the first eight; more decompositions exist.
