Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521684, here are decompositions:

37 + 33521647 = 33521684
61 + 33521623 = 33521684
223 + 33521461 = 33521684
283 + 33521401 = 33521684
463 + 33521221 = 33521684
601 + 33521083 = 33521684
883 + 33520801 = 33521684
907 + 33520777 = 33521684

Showing the first eight; more decompositions exist.
