Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556180, here are decompositions:

23 + 33556157 = 33556180
191 + 33555989 = 33556180
233 + 33555947 = 33556180
443 + 33555737 = 33556180
479 + 33555701 = 33556180
521 + 33555659 = 33556180
563 + 33555617 = 33556180
569 + 33555611 = 33556180

Showing the first eight; more decompositions exist.
