Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488820, here are decompositions:

31 + 33488789 = 33488820
41 + 33488779 = 33488820
73 + 33488747 = 33488820
103 + 33488717 = 33488820
137 + 33488683 = 33488820
139 + 33488681 = 33488820
151 + 33488669 = 33488820
173 + 33488647 = 33488820

Showing the first eight; more decompositions exist.
