Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470574, here are decompositions:

  • 11 + 31470563 = 31470574
  • 17 + 31470557 = 31470574
  • 131 + 31470443 = 31470574
  • 251 + 31470323 = 31470574
  • 281 + 31470293 = 31470574
  • 353 + 31470221 = 31470574
  • 431 + 31470143 = 31470574
  • 587 + 31469987 = 31470574

Showing the first eight; more decompositions exist.
