Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473042, here are decompositions:

  • 83 + 2147472959 = 2147473042
  • 149 + 2147472893 = 2147473042
  • 179 + 2147472863 = 2147473042
  • 353 + 2147472689 = 2147473042
  • 359 + 2147472683 = 2147473042
  • 383 + 2147472659 = 2147473042
  • 431 + 2147472611 = 2147473042
  • 593 + 2147472449 = 2147473042

Showing the first eight; more decompositions exist.
