Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473274, here are decompositions:

  • 7 + 2147473267 = 2147473274
  • 43 + 2147473231 = 2147473274
  • 157 + 2147473117 = 2147473274
  • 487 + 2147472787 = 2147473274
  • 523 + 2147472751 = 2147473274
  • 577 + 2147472697 = 2147473274
  • 673 + 2147472601 = 2147473274
  • 853 + 2147472421 = 2147473274

Showing the first eight; more decompositions exist.
