Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474266, here are decompositions:

  • 53 + 2147474213 = 2147474266
  • 107 + 2147474159 = 2147474266
  • 173 + 2147474093 = 2147474266
  • 239 + 2147474027 = 2147474266
  • 257 + 2147474009 = 2147474266
  • 479 + 2147473787 = 2147474266
  • 503 + 2147473763 = 2147474266
  • 563 + 2147473703 = 2147474266

Showing the first eight; more decompositions exist.
