Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603820, here are decompositions:

23 + 33603797 = 33603820
53 + 33603767 = 33603820
113 + 33603707 = 33603820
227 + 33603593 = 33603820
233 + 33603587 = 33603820
251 + 33603569 = 33603820
281 + 33603539 = 33603820
293 + 33603527 = 33603820

Showing the first eight; more decompositions exist.
