Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545772, here are decompositions:

59 + 33545713 = 33545772
79 + 33545693 = 33545772
149 + 33545623 = 33545772
163 + 33545609 = 33545772
173 + 33545599 = 33545772
181 + 33545591 = 33545772
193 + 33545579 = 33545772
313 + 33545459 = 33545772

Showing the first eight; more decompositions exist.
