Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 34780, here are decompositions:

  • 17 + 34763 = 34780
  • 23 + 34757 = 34780
  • 41 + 34739 = 34780
  • 59 + 34721 = 34780
  • 101 + 34679 = 34780
  • 107 + 34673 = 34780
  • 113 + 34667 = 34780
  • 131 + 34649 = 34780

Showing the first eight; more decompositions exist.
