Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480990, here are decompositions:

13 + 33480977 = 33480990
19 + 33480971 = 33480990
43 + 33480947 = 33480990
47 + 33480943 = 33480990
61 + 33480929 = 33480990
73 + 33480917 = 33480990
139 + 33480851 = 33480990
157 + 33480833 = 33480990

Showing the first eight; more decompositions exist.
