Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467538, here are decompositions:

  • 67 + 2147467471 = 2147467538
  • 199 + 2147467339 = 2147467538
  • 211 + 2147467327 = 2147467538
  • 277 + 2147467261 = 2147467538
  • 547 + 2147466991 = 2147467538
  • 607 + 2147466931 = 2147467538
  • 691 + 2147466847 = 2147467538
  • 751 + 2147466787 = 2147467538

Showing the first eight; more decompositions exist.
