Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474372, here are decompositions:

  • 29 + 31474343 = 31474372
  • 53 + 31474319 = 31474372
  • 71 + 31474301 = 31474372
  • 311 + 31474061 = 31474372
  • 401 + 31473971 = 31474372
  • 509 + 31473863 = 31474372
  • 563 + 31473809 = 31474372
  • 593 + 31473779 = 31474372

Showing the first eight; more decompositions exist.
