Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488778, here are decompositions:

7 + 33488771 = 33488778
31 + 33488747 = 33488778
61 + 33488717 = 33488778
97 + 33488681 = 33488778
109 + 33488669 = 33488778
131 + 33488647 = 33488778
139 + 33488639 = 33488778
151 + 33488627 = 33488778

Showing the first eight; more decompositions exist.
