Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545688, here are decompositions:

31 + 33545657 = 33545688
37 + 33545651 = 33545688
79 + 33545609 = 33545688
89 + 33545599 = 33545688
97 + 33545591 = 33545688
109 + 33545579 = 33545688
131 + 33545557 = 33545688
191 + 33545497 = 33545688

Showing the first eight; more decompositions exist.
