Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530878, here are decompositions:

41 + 33530837 = 33530878
89 + 33530789 = 33530878
137 + 33530741 = 33530878
149 + 33530729 = 33530878
281 + 33530597 = 33530878
431 + 33530447 = 33530878
509 + 33530369 = 33530878
569 + 33530309 = 33530878

Showing the first eight; more decompositions exist.
