Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723884, here are decompositions:

  • 5 + 8723879 = 8723884
  • 353 + 8723531 = 8723884
  • 401 + 8723483 = 8723884
  • 443 + 8723441 = 8723884
  • 461 + 8723423 = 8723884
  • 563 + 8723321 = 8723884
  • 641 + 8723243 = 8723884
  • 761 + 8723123 = 8723884

Showing the first eight; more decompositions exist.
