Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147566798, here are decompositions:

  • 17 + 2147566781 = 2147566798
  • 137 + 2147566661 = 2147566798
  • 239 + 2147566559 = 2147566798
  • 359 + 2147566439 = 2147566798
  • 431 + 2147566367 = 2147566798
  • 467 + 2147566331 = 2147566798
  • 521 + 2147566277 = 2147566798
  • 647 + 2147566151 = 2147566798

Showing the first eight; more decompositions exist.
