Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488142, here are decompositions:

5 + 33488137 = 33488142
11 + 33488131 = 33488142
19 + 33488123 = 33488142
41 + 33488101 = 33488142
101 + 33488041 = 33488142
109 + 33488033 = 33488142
139 + 33488003 = 33488142
173 + 33487969 = 33488142

Showing the first eight; more decompositions exist.
