Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487138, here are decompositions:

  • 17 + 33487121 = 33487138
  • 89 + 33487049 = 33487138
  • 107 + 33487031 = 33487138
  • 197 + 33486941 = 33487138
  • 281 + 33486857 = 33487138
  • 389 + 33486749 = 33487138
  • 467 + 33486671 = 33487138
  • 557 + 33486581 = 33487138

Showing the first eight; more decompositions exist.
