Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531760, here are decompositions:

11 + 33531749 = 33531760
23 + 33531737 = 33531760
89 + 33531671 = 33531760
107 + 33531653 = 33531760
149 + 33531611 = 33531760
173 + 33531587 = 33531760
233 + 33531527 = 33531760
257 + 33531503 = 33531760

Showing the first eight; more decompositions exist.
