Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33495820, here are decompositions:

101 + 33495719 = 33495820
167 + 33495653 = 33495820
233 + 33495587 = 33495820
251 + 33495569 = 33495820
311 + 33495509 = 33495820
317 + 33495503 = 33495820
383 + 33495437 = 33495820
401 + 33495419 = 33495820

Showing the first eight; more decompositions exist.
