Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147589090, here are decompositions:

  • 7 + 2147589083 = 2147589090
  • 19 + 2147589071 = 2147589090
  • 37 + 2147589053 = 2147589090
  • 41 + 2147589049 = 2147589090
  • 43 + 2147589047 = 2147589090
  • 79 + 2147589011 = 2147589090
  • 83 + 2147589007 = 2147589090
  • 103 + 2147588987 = 2147589090

Showing the first eight; more decompositions exist.
