Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526516, here are decompositions:

  • 13 + 31526503 = 31526516
  • 19 + 31526497 = 31526516
  • 97 + 31526419 = 31526516
  • 127 + 31526389 = 31526516
  • 157 + 31526359 = 31526516
  • 199 + 31526317 = 31526516
  • 277 + 31526239 = 31526516
  • 433 + 31526083 = 31526516

Showing the first eight; more decompositions exist.
