Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678200, here are decompositions:

  • 53 + 8678147 = 8678200
  • 59 + 8678141 = 8678200
  • 71 + 8678129 = 8678200
  • 107 + 8678093 = 8678200
  • 131 + 8678069 = 8678200
  • 137 + 8678063 = 8678200
  • 149 + 8678051 = 8678200
  • 173 + 8678027 = 8678200

Showing the first eight; more decompositions exist.
