Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443284, here are decompositions:

  • 61 + 2147443223 = 2147443284
  • 73 + 2147443211 = 2147443284
  • 113 + 2147443171 = 2147443284
  • 127 + 2147443157 = 2147443284
  • 163 + 2147443121 = 2147443284
  • 197 + 2147443087 = 2147443284
  • 227 + 2147443057 = 2147443284
  • 251 + 2147443033 = 2147443284

Showing the first eight; more decompositions exist.
