Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489730, here are decompositions:

  • 13 + 2147489717 = 2147489730
  • 17 + 2147489713 = 2147489730
  • 31 + 2147489699 = 2147489730
  • 79 + 2147489651 = 2147489730
  • 151 + 2147489579 = 2147489730
  • 193 + 2147489537 = 2147489730
  • 227 + 2147489503 = 2147489730
  • 257 + 2147489473 = 2147489730

Showing the first eight; more decompositions exist.

IPv4 address
