Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147573758, here are decompositions:

  • 101 + 2147573657 = 2147573758
  • 107 + 2147573651 = 2147573758
  • 149 + 2147573609 = 2147573758
  • 311 + 2147573447 = 2147573758
  • 389 + 2147573369 = 2147573758
  • 587 + 2147573171 = 2147573758
  • 641 + 2147573117 = 2147573758
  • 809 + 2147572949 = 2147573758

Showing the first eight; more decompositions exist.
