Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723522, here are decompositions:

  • 43 + 8723479 = 8723522
  • 103 + 8723419 = 8723522
  • 163 + 8723359 = 8723522
  • 211 + 8723311 = 8723522
  • 331 + 8723191 = 8723522
  • 373 + 8723149 = 8723522
  • 433 + 8723089 = 8723522
  • 523 + 8722999 = 8723522

Showing the first eight; more decompositions exist.
