Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581420, here are decompositions:

7 + 33581413 = 33581420
139 + 33581281 = 33581420
157 + 33581263 = 33581420
163 + 33581257 = 33581420
199 + 33581221 = 33581420
211 + 33581209 = 33581420
409 + 33581011 = 33581420
463 + 33580957 = 33581420

Showing the first eight; more decompositions exist.
