Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497580, here are decompositions:

  • 73 + 2147497507 = 2147497580
  • 337 + 2147497243 = 2147497580
  • 379 + 2147497201 = 2147497580
  • 439 + 2147497141 = 2147497580
  • 499 + 2147497081 = 2147497580
  • 541 + 2147497039 = 2147497580
  • 601 + 2147496979 = 2147497580
  • 619 + 2147496961 = 2147497580

Showing the first eight; more decompositions exist.
