Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147531090, here are decompositions:

  • 73 + 2147531017 = 2147531090
  • 127 + 2147530963 = 2147531090
  • 139 + 2147530951 = 2147531090
  • 223 + 2147530867 = 2147531090
  • 349 + 2147530741 = 2147531090
  • 379 + 2147530711 = 2147531090
  • 421 + 2147530669 = 2147531090
  • 547 + 2147530543 = 2147531090

Showing the first eight; more decompositions exist.
