Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427194, here are decompositions:

  • 37 + 2147427157 = 2147427194
  • 43 + 2147427151 = 2147427194
  • 103 + 2147427091 = 2147427194
  • 151 + 2147427043 = 2147427194
  • 193 + 2147427001 = 2147427194
  • 223 + 2147426971 = 2147427194
  • 373 + 2147426821 = 2147427194
  • 571 + 2147426623 = 2147427194

Showing the first eight; more decompositions exist.
