Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294979172, here are decompositions:

  • 5 + 4294979167 = 4294979172
  • 13 + 4294979159 = 4294979172
  • 19 + 4294979153 = 4294979172
  • 61 + 4294979111 = 4294979172
  • 103 + 4294979069 = 4294979172
  • 139 + 4294979033 = 4294979172
  • 149 + 4294979023 = 4294979172
  • 163 + 4294979009 = 4294979172

Showing the first eight; more decompositions exist.
