Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942780, here are decompositions:

  • 17 + 942763 = 942780
  • 31 + 942749 = 942780
  • 53 + 942727 = 942780
  • 61 + 942719 = 942780
  • 71 + 942709 = 942780
  • 89 + 942691 = 942780
  • 127 + 942653 = 942780
  • 173 + 942607 = 942780

Showing the first eight; more decompositions exist.
