Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147553194, here are decompositions:

  • 13 + 2147553181 = 2147553194
  • 37 + 2147553157 = 2147553194
  • 43 + 2147553151 = 2147553194
  • 103 + 2147553091 = 2147553194
  • 151 + 2147553043 = 2147553194
  • 211 + 2147552983 = 2147553194
  • 271 + 2147552923 = 2147553194
  • 307 + 2147552887 = 2147553194

Showing the first eight; more decompositions exist.
