Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521070, here are decompositions:

13 + 33521057 = 33521070
31 + 33521039 = 33521070
61 + 33521009 = 33521070
67 + 33521003 = 33521070
83 + 33520987 = 33521070
97 + 33520973 = 33521070
103 + 33520967 = 33521070
131 + 33520939 = 33521070

Showing the first eight; more decompositions exist.
