Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992640, here are decompositions:

  • 167 + 4294992473 = 4294992640
  • 173 + 4294992467 = 4294992640
  • 227 + 4294992413 = 4294992640
  • 443 + 4294992197 = 4294992640
  • 563 + 4294992077 = 4294992640
  • 569 + 4294992071 = 4294992640
  • 1061 + 4294991579 = 4294992640
  • 1193 + 4294991447 = 4294992640

Showing the first eight; more decompositions exist.
