Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743490, here are decompositions:

  • 31 + 8743459 = 8743490
  • 37 + 8743453 = 8743490
  • 43 + 8743447 = 8743490
  • 73 + 8743417 = 8743490
  • 79 + 8743411 = 8743490
  • 97 + 8743393 = 8743490
  • 163 + 8743327 = 8743490
  • 181 + 8743309 = 8743490

Showing the first eight; more decompositions exist.
