Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572620, here are decompositions:

83 + 33572537 = 33572620
131 + 33572489 = 33572620
173 + 33572447 = 33572620
239 + 33572381 = 33572620
269 + 33572351 = 33572620
281 + 33572339 = 33572620
311 + 33572309 = 33572620
317 + 33572303 = 33572620

Showing the first eight; more decompositions exist.
