Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497546, here are decompositions:

  • 23 + 2147497523 = 2147497546
  • 53 + 2147497493 = 2147497546
  • 197 + 2147497349 = 2147497546
  • 503 + 2147497043 = 2147497546
  • 683 + 2147496863 = 2147497546
  • 839 + 2147496707 = 2147497546
  • 977 + 2147496569 = 2147497546
  • 1109 + 2147496437 = 2147497546

Showing the first eight; more decompositions exist.
