Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429016, here are decompositions:

  • 13 + 2147429003 = 2147429016
  • 17 + 2147428999 = 2147429016
  • 59 + 2147428957 = 2147429016
  • 67 + 2147428949 = 2147429016
  • 179 + 2147428837 = 2147429016
  • 193 + 2147428823 = 2147429016
  • 197 + 2147428819 = 2147429016
  • 223 + 2147428793 = 2147429016

Showing the first eight; more decompositions exist.
