Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466894, here are decompositions:

  • 47 + 2147466847 = 2147466894
  • 61 + 2147466833 = 2147466894
  • 101 + 2147466793 = 2147466894
  • 107 + 2147466787 = 2147466894
  • 173 + 2147466721 = 2147466894
  • 193 + 2147466701 = 2147466894
  • 211 + 2147466683 = 2147466894
  • 347 + 2147466547 = 2147466894

Showing the first eight; more decompositions exist.
