Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472770, here are decompositions:

  • 13 + 2147472757 = 2147472770
  • 19 + 2147472751 = 2147472770
  • 73 + 2147472697 = 2147472770
  • 271 + 2147472499 = 2147472770
  • 349 + 2147472421 = 2147472770
  • 397 + 2147472373 = 2147472770
  • 571 + 2147472199 = 2147472770
  • 661 + 2147472109 = 2147472770

Showing the first eight; more decompositions exist.
