Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497386, here are decompositions:

  • 37 + 2147497349 = 2147497386
  • 149 + 2147497237 = 2147497386
  • 347 + 2147497039 = 2147497386
  • 367 + 2147497019 = 2147497386
  • 389 + 2147496997 = 2147497386
  • 449 + 2147496937 = 2147497386
  • 523 + 2147496863 = 2147497386
  • 547 + 2147496839 = 2147497386

Showing the first eight; more decompositions exist.
