Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543606, here are decompositions:

  • 257 + 31543349 = 31543606
  • 383 + 31543223 = 31543606
  • 389 + 31543217 = 31543606
  • 443 + 31543163 = 31543606
  • 503 + 31543103 = 31543606
  • 587 + 31543019 = 31543606
  • 797 + 31542809 = 31543606
  • 839 + 31542767 = 31543606

Showing the first eight; more decompositions exist.
