Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650220, here are decompositions:

  • 3 + 8650217 = 8650220
  • 31 + 8650189 = 8650220
  • 67 + 8650153 = 8650220
  • 79 + 8650141 = 8650220
  • 97 + 8650123 = 8650220
  • 181 + 8650039 = 8650220
  • 193 + 8650027 = 8650220
  • 283 + 8649937 = 8650220

Showing the first eight; more decompositions exist.
