Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472464, here are decompositions:

  • 43 + 2147472421 = 2147472464
  • 331 + 2147472133 = 2147472464
  • 373 + 2147472091 = 2147472464
  • 421 + 2147472043 = 2147472464
  • 601 + 2147471863 = 2147472464
  • 757 + 2147471707 = 2147472464
  • 853 + 2147471611 = 2147472464
  • 883 + 2147471581 = 2147472464

Showing the first eight; more decompositions exist.
