Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489974, here are decompositions:

  • 5 + 2147489969 = 2147489974
  • 17 + 2147489957 = 2147489974
  • 101 + 2147489873 = 2147489974
  • 131 + 2147489843 = 2147489974
  • 257 + 2147489717 = 2147489974
  • 431 + 2147489543 = 2147489974
  • 491 + 2147489483 = 2147489974
  • 677 + 2147489297 = 2147489974

Showing the first eight; more decompositions exist.

IPv4 address
