Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553878, here are decompositions:

41 + 33553837 = 33553878
79 + 33553799 = 33553878
107 + 33553771 = 33553878
109 + 33553769 = 33553878
131 + 33553747 = 33553878
139 + 33553739 = 33553878
151 + 33553727 = 33553878
181 + 33553697 = 33553878

Showing the first eight; more decompositions exist.
