Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473450, here are decompositions:

  • 41 + 2147473409 = 2147473450
  • 149 + 2147473301 = 2147473450
  • 167 + 2147473283 = 2147473450
  • 233 + 2147473217 = 2147473450
  • 263 + 2147473187 = 2147473450
  • 389 + 2147473061 = 2147473450
  • 401 + 2147473049 = 2147473450
  • 491 + 2147472959 = 2147473450

Showing the first eight; more decompositions exist.
