Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572872, here are decompositions:

23 + 33572849 = 33572872
59 + 33572813 = 33572872
131 + 33572741 = 33572872
173 + 33572699 = 33572872
383 + 33572489 = 33572872
491 + 33572381 = 33572872
521 + 33572351 = 33572872
563 + 33572309 = 33572872

Showing the first eight; more decompositions exist.
