Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38218, here are decompositions:

  • 17 + 38201 = 38218
  • 29 + 38189 = 38218
  • 41 + 38177 = 38218
  • 149 + 38069 = 38218
  • 179 + 38039 = 38218
  • 227 + 37991 = 38218
  • 251 + 37967 = 38218
  • 311 + 37907 = 38218

Showing the first eight; more decompositions exist.
