Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497906, here are decompositions:

  • 5 + 2147497901 = 2147497906
  • 17 + 2147497889 = 2147497906
  • 137 + 2147497769 = 2147497906
  • 149 + 2147497757 = 2147497906
  • 173 + 2147497733 = 2147497906
  • 347 + 2147497559 = 2147497906
  • 383 + 2147497523 = 2147497906
  • 503 + 2147497403 = 2147497906

Showing the first eight; more decompositions exist.
