Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501690, here are decompositions:

  • 7 + 2147501683 = 2147501690
  • 13 + 2147501677 = 2147501690
  • 67 + 2147501623 = 2147501690
  • 73 + 2147501617 = 2147501690
  • 79 + 2147501611 = 2147501690
  • 211 + 2147501479 = 2147501690
  • 457 + 2147501233 = 2147501690
  • 547 + 2147501143 = 2147501690

Showing the first eight; more decompositions exist.
