Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489380, here are decompositions:

3 + 33489377 = 33489380
19 + 33489361 = 33489380
31 + 33489349 = 33489380
61 + 33489319 = 33489380
97 + 33489283 = 33489380
139 + 33489241 = 33489380
157 + 33489223 = 33489380
229 + 33489151 = 33489380

Showing the first eight; more decompositions exist.
