Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679240, here are decompositions:

  • 19 + 8679221 = 8679240
  • 23 + 8679217 = 8679240
  • 41 + 8679199 = 8679240
  • 47 + 8679193 = 8679240
  • 61 + 8679179 = 8679240
  • 103 + 8679137 = 8679240
  • 131 + 8679109 = 8679240
  • 181 + 8679059 = 8679240

Showing the first eight; more decompositions exist.
