Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147527902, here are decompositions:

  • 5 + 2147527897 = 2147527902
  • 41 + 2147527861 = 2147527902
  • 43 + 2147527859 = 2147527902
  • 83 + 2147527819 = 2147527902
  • 89 + 2147527813 = 2147527902
  • 103 + 2147527799 = 2147527902
  • 263 + 2147527639 = 2147527902
  • 293 + 2147527609 = 2147527902

Showing the first eight; more decompositions exist.
