Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521858, here are decompositions:

31 + 33521827 = 33521858
37 + 33521821 = 33521858
61 + 33521797 = 33521858
127 + 33521731 = 33521858
157 + 33521701 = 33521858
211 + 33521647 = 33521858
229 + 33521629 = 33521858
397 + 33521461 = 33521858

Showing the first eight; more decompositions exist.
