Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723750, here are decompositions:

  • 19 + 8723731 = 8723750
  • 43 + 8723707 = 8723750
  • 73 + 8723677 = 8723750
  • 97 + 8723653 = 8723750
  • 157 + 8723593 = 8723750
  • 181 + 8723569 = 8723750
  • 199 + 8723551 = 8723750
  • 229 + 8723521 = 8723750

Showing the first eight; more decompositions exist.
