Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33562578, here are decompositions:

29 + 33562549 = 33562578
31 + 33562547 = 33562578
151 + 33562427 = 33562578
157 + 33562421 = 33562578
167 + 33562411 = 33562578
191 + 33562387 = 33562578
197 + 33562381 = 33562578
229 + 33562349 = 33562578

Showing the first eight; more decompositions exist.
