Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521768, here are decompositions:

37 + 33521731 = 33521768
67 + 33521701 = 33521768
79 + 33521689 = 33521768
139 + 33521629 = 33521768
229 + 33521539 = 33521768
307 + 33521461 = 33521768
331 + 33521437 = 33521768
337 + 33521431 = 33521768

Showing the first eight; more decompositions exist.
