Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473208, here are decompositions:

  • 421 + 2147472787 = 2147473208
  • 457 + 2147472751 = 2147473208
  • 607 + 2147472601 = 2147473208
  • 709 + 2147472499 = 2147473208
  • 739 + 2147472469 = 2147473208
  • 787 + 2147472421 = 2147473208
  • 919 + 2147472289 = 2147473208
  • 1009 + 2147472199 = 2147473208

Showing the first eight; more decompositions exist.
