Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538842, here are decompositions:

19 + 33538823 = 33538842
41 + 33538801 = 33538842
59 + 33538783 = 33538842
79 + 33538763 = 33538842
83 + 33538759 = 33538842
101 + 33538741 = 33538842
131 + 33538711 = 33538842
163 + 33538679 = 33538842

Showing the first eight; more decompositions exist.
