Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551142, here are decompositions:

13 + 33551129 = 33551142
29 + 33551113 = 33551142
43 + 33551099 = 33551142
89 + 33551053 = 33551142
101 + 33551041 = 33551142
109 + 33551033 = 33551142
139 + 33551003 = 33551142
193 + 33550949 = 33551142

Showing the first eight; more decompositions exist.
