Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670844, here are decompositions:

  • 53 + 8670791 = 8670844
  • 71 + 8670773 = 8670844
  • 101 + 8670743 = 8670844
  • 131 + 8670713 = 8670844
  • 191 + 8670653 = 8670844
  • 233 + 8670611 = 8670844
  • 293 + 8670551 = 8670844
  • 311 + 8670533 = 8670844

Showing the first eight; more decompositions exist.
