Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147380994, here are decompositions:

  • 37 + 2147380957 = 2147380994
  • 127 + 2147380867 = 2147380994
  • 163 + 2147380831 = 2147380994
  • 193 + 2147380801 = 2147380994
  • 211 + 2147380783 = 2147380994
  • 313 + 2147380681 = 2147380994
  • 331 + 2147380663 = 2147380994
  • 457 + 2147380537 = 2147380994

Showing the first eight; more decompositions exist.
