Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474624, here are decompositions:

  • 23 + 31474601 = 31474624
  • 47 + 31474577 = 31474624
  • 53 + 31474571 = 31474624
  • 191 + 31474433 = 31474624
  • 227 + 31474397 = 31474624
  • 281 + 31474343 = 31474624
  • 317 + 31474307 = 31474624
  • 563 + 31474061 = 31474624

Showing the first eight; more decompositions exist.
