Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472974, here are decompositions:

  • 223 + 2147472751 = 2147472974
  • 277 + 2147472697 = 2147472974
  • 373 + 2147472601 = 2147472974
  • 601 + 2147472373 = 2147472974
  • 631 + 2147472343 = 2147472974
  • 883 + 2147472091 = 2147472974
  • 937 + 2147472037 = 2147472974
  • 1093 + 2147471881 = 2147472974

Showing the first eight; more decompositions exist.
