Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670780, here are decompositions:

  • 7 + 8670773 = 8670780
  • 29 + 8670751 = 8670780
  • 37 + 8670743 = 8670780
  • 67 + 8670713 = 8670780
  • 71 + 8670709 = 8670780
  • 101 + 8670679 = 8670780
  • 113 + 8670667 = 8670780
  • 127 + 8670653 = 8670780

Showing the first eight; more decompositions exist.
