Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427494, here are decompositions:

  • 67 + 2147427427 = 2147427494
  • 97 + 2147427397 = 2147427494
  • 337 + 2147427157 = 2147427494
  • 523 + 2147426971 = 2147427494
  • 673 + 2147426821 = 2147427494
  • 853 + 2147426641 = 2147427494
  • 937 + 2147426557 = 2147427494
  • 967 + 2147426527 = 2147427494

Showing the first eight; more decompositions exist.
