Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704220, here are decompositions:

  • 37 + 8704183 = 8704220
  • 61 + 8704159 = 8704220
  • 97 + 8704123 = 8704220
  • 103 + 8704117 = 8704220
  • 193 + 8704027 = 8704220
  • 277 + 8703943 = 8704220
  • 331 + 8703889 = 8704220
  • 367 + 8703853 = 8704220

Showing the first eight; more decompositions exist.
