Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467786, here are decompositions:

  • 17 + 2147467769 = 2147467786
  • 53 + 2147467733 = 2147467786
  • 89 + 2147467697 = 2147467786
  • 227 + 2147467559 = 2147467786
  • 293 + 2147467493 = 2147467786
  • 383 + 2147467403 = 2147467786
  • 419 + 2147467367 = 2147467786
  • 617 + 2147467169 = 2147467786

Showing the first eight; more decompositions exist.
