Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467490, here are decompositions:

  • 19 + 2147467471 = 2147467490
  • 97 + 2147467393 = 2147467490
  • 151 + 2147467339 = 2147467490
  • 163 + 2147467327 = 2147467490
  • 229 + 2147467261 = 2147467490
  • 271 + 2147467219 = 2147467490
  • 397 + 2147467093 = 2147467490
  • 433 + 2147467057 = 2147467490

Showing the first eight; more decompositions exist.
