Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147400922, here are decompositions:

  • 101 + 2147400821 = 2147400922
  • 179 + 2147400743 = 2147400922
  • 239 + 2147400683 = 2147400922
  • 593 + 2147400329 = 2147400922
  • 683 + 2147400239 = 2147400922
  • 809 + 2147400113 = 2147400922
  • 911 + 2147400011 = 2147400922
  • 941 + 2147399981 = 2147400922

Showing the first eight; more decompositions exist.
