Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147526180, here are decompositions:

  • 17 + 2147526163 = 2147526180
  • 29 + 2147526151 = 2147526180
  • 31 + 2147526149 = 2147526180
  • 53 + 2147526127 = 2147526180
  • 71 + 2147526109 = 2147526180
  • 101 + 2147526079 = 2147526180
  • 131 + 2147526049 = 2147526180
  • 139 + 2147526041 = 2147526180

Showing the first eight; more decompositions exist.
