Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731922, here are decompositions:

  • 61 + 8731861 = 8731922
  • 103 + 8731819 = 8731922
  • 139 + 8731783 = 8731922
  • 211 + 8731711 = 8731922
  • 223 + 8731699 = 8731922
  • 313 + 8731609 = 8731922
  • 421 + 8731501 = 8731922
  • 541 + 8731381 = 8731922

Showing the first eight; more decompositions exist.
