Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530842, here are decompositions:

5 + 33530837 = 33530842
29 + 33530813 = 33530842
53 + 33530789 = 33530842
83 + 33530759 = 33530842
101 + 33530741 = 33530842
113 + 33530729 = 33530842
563 + 33530279 = 33530842
593 + 33530249 = 33530842

Showing the first eight; more decompositions exist.
