Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491156, here are decompositions:

3 + 33491153 = 33491156
7 + 33491149 = 33491156
157 + 33490999 = 33491156
229 + 33490927 = 33491156
313 + 33490843 = 33491156
379 + 33490777 = 33491156
409 + 33490747 = 33491156
463 + 33490693 = 33491156

Showing the first eight; more decompositions exist.
