Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470550, here are decompositions:

  • 3 + 31470547 = 31470550
  • 107 + 31470443 = 31470550
  • 191 + 31470359 = 31470550
  • 197 + 31470353 = 31470550
  • 227 + 31470323 = 31470550
  • 257 + 31470293 = 31470550
  • 383 + 31470167 = 31470550
  • 563 + 31469987 = 31470550

Showing the first eight; more decompositions exist.
