Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475770, here are decompositions:

  • 89 + 31475681 = 31475770
  • 101 + 31475669 = 31475770
  • 173 + 31475597 = 31475770
  • 191 + 31475579 = 31475770
  • 281 + 31475489 = 31475770
  • 311 + 31475459 = 31475770
  • 317 + 31475453 = 31475770
  • 383 + 31475387 = 31475770

Showing the first eight; more decompositions exist.
