Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485140, here are decompositions:

  • 7 + 2147485133 = 2147485140
  • 19 + 2147485121 = 2147485140
  • 43 + 2147485097 = 2147485140
  • 61 + 2147485079 = 2147485140
  • 67 + 2147485073 = 2147485140
  • 83 + 2147485057 = 2147485140
  • 149 + 2147484991 = 2147485140
  • 179 + 2147484961 = 2147485140

Showing the first eight; more decompositions exist.
