Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723722, here are decompositions:

  • 83 + 8723639 = 8723722
  • 113 + 8723609 = 8723722
  • 191 + 8723531 = 8723722
  • 239 + 8723483 = 8723722
  • 263 + 8723459 = 8723722
  • 281 + 8723441 = 8723722
  • 401 + 8723321 = 8723722
  • 419 + 8723303 = 8723722

Showing the first eight; more decompositions exist.
