Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577572, here are decompositions:

43 + 33577529 = 33577572
59 + 33577513 = 33577572
71 + 33577501 = 33577572
113 + 33577459 = 33577572
191 + 33577381 = 33577572
199 + 33577373 = 33577572
229 + 33577343 = 33577572
233 + 33577339 = 33577572

Showing the first eight; more decompositions exist.
