Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472782, here are decompositions:

  • 31 + 2147472751 = 2147472782
  • 181 + 2147472601 = 2147472782
  • 283 + 2147472499 = 2147472782
  • 313 + 2147472469 = 2147472782
  • 409 + 2147472373 = 2147472782
  • 439 + 2147472343 = 2147472782
  • 523 + 2147472259 = 2147472782
  • 673 + 2147472109 = 2147472782

Showing the first eight; more decompositions exist.
