Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497772, here are decompositions:

  • 3 + 2147497769 = 2147497772
  • 73 + 2147497699 = 2147497772
  • 109 + 2147497663 = 2147497772
  • 283 + 2147497489 = 2147497772
  • 313 + 2147497459 = 2147497772
  • 379 + 2147497393 = 2147497772
  • 571 + 2147497201 = 2147497772
  • 631 + 2147497141 = 2147497772

Showing the first eight; more decompositions exist.
