Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723760, here are decompositions:

  • 29 + 8723731 = 8723760
  • 53 + 8723707 = 8723760
  • 83 + 8723677 = 8723760
  • 107 + 8723653 = 8723760
  • 151 + 8723609 = 8723760
  • 167 + 8723593 = 8723760
  • 191 + 8723569 = 8723760
  • 229 + 8723531 = 8723760

Showing the first eight; more decompositions exist.
