Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469258, here are decompositions:

  • 19 + 2147469239 = 2147469258
  • 29 + 2147469229 = 2147469258
  • 71 + 2147469187 = 2147469258
  • 79 + 2147469179 = 2147469258
  • 101 + 2147469157 = 2147469258
  • 127 + 2147469131 = 2147469258
  • 157 + 2147469101 = 2147469258
  • 191 + 2147469067 = 2147469258

Showing the first eight; more decompositions exist.
