Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572380, here are decompositions:

3 + 33572377 = 33572380
29 + 33572351 = 33572380
41 + 33572339 = 33572380
47 + 33572333 = 33572380
71 + 33572309 = 33572380
239 + 33572141 = 33572380
263 + 33572117 = 33572380
353 + 33572027 = 33572380

Showing the first eight; more decompositions exist.
