Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544890, here are decompositions:

13 + 33544877 = 33544890
19 + 33544871 = 33544890
23 + 33544867 = 33544890
47 + 33544843 = 33544890
79 + 33544811 = 33544890
107 + 33544783 = 33544890
109 + 33544781 = 33544890
151 + 33544739 = 33544890

Showing the first eight; more decompositions exist.
