Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572812, here are decompositions:

71 + 33572741 = 33572812
113 + 33572699 = 33572812
431 + 33572381 = 33572812
461 + 33572351 = 33572812
479 + 33572333 = 33572812
503 + 33572309 = 33572812
509 + 33572303 = 33572812
593 + 33572219 = 33572812

Showing the first eight; more decompositions exist.
