Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513870, here are decompositions:

7 + 33513863 = 33513870
11 + 33513859 = 33513870
29 + 33513841 = 33513870
31 + 33513839 = 33513870
59 + 33513811 = 33513870
73 + 33513797 = 33513870
109 + 33513761 = 33513870
139 + 33513731 = 33513870

Showing the first eight; more decompositions exist.
