Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427236, here are decompositions:

  • 7 + 2147427229 = 2147427236
  • 67 + 2147427169 = 2147427236
  • 79 + 2147427157 = 2147427236
  • 193 + 2147427043 = 2147427236
  • 607 + 2147426629 = 2147427236
  • 613 + 2147426623 = 2147427236
  • 709 + 2147426527 = 2147427236
  • 739 + 2147426497 = 2147427236

Showing the first eight; more decompositions exist.
