Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501942, here are decompositions:

  • 193 + 2147501749 = 2147501942
  • 331 + 2147501611 = 2147501942
  • 463 + 2147501479 = 2147501942
  • 499 + 2147501443 = 2147501942
  • 709 + 2147501233 = 2147501942
  • 769 + 2147501173 = 2147501942
  • 811 + 2147501131 = 2147501942
  • 853 + 2147501089 = 2147501942

Showing the first eight; more decompositions exist.
