Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497820, here are decompositions:

  • 103 + 2147497717 = 2147497820
  • 157 + 2147497663 = 2147497820
  • 313 + 2147497507 = 2147497820
  • 331 + 2147497489 = 2147497820
  • 373 + 2147497447 = 2147497820
  • 409 + 2147497411 = 2147497820
  • 499 + 2147497321 = 2147497820
  • 577 + 2147497243 = 2147497820

Showing the first eight; more decompositions exist.
