Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147442202, here are decompositions:

  • 11 + 2147442191 = 2147442202
  • 23 + 2147442179 = 2147442202
  • 71 + 2147442131 = 2147442202
  • 83 + 2147442119 = 2147442202
  • 131 + 2147442071 = 2147442202
  • 149 + 2147442053 = 2147442202
  • 173 + 2147442029 = 2147442202
  • 239 + 2147441963 = 2147442202

Showing the first eight; more decompositions exist.
