Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472670, here are decompositions:

  • 11 + 2147472659 = 2147472670
  • 53 + 2147472617 = 2147472670
  • 59 + 2147472611 = 2147472670
  • 113 + 2147472557 = 2147472670
  • 179 + 2147472491 = 2147472670
  • 227 + 2147472443 = 2147472670
  • 257 + 2147472413 = 2147472670
  • 293 + 2147472377 = 2147472670

Showing the first eight; more decompositions exist.
