Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147420662, here are decompositions:

  • 5 + 2147420657 = 2147420662
  • 389 + 2147420273 = 2147420662
  • 479 + 2147420183 = 2147420662
  • 509 + 2147420153 = 2147420662
  • 593 + 2147420069 = 2147420662
  • 683 + 2147419979 = 2147420662
  • 701 + 2147419961 = 2147420662
  • 719 + 2147419943 = 2147420662

Showing the first eight; more decompositions exist.
