Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490172, here are decompositions:

193 + 33489979 = 33490172
211 + 33489961 = 33490172
229 + 33489943 = 33490172
241 + 33489931 = 33490172
271 + 33489901 = 33490172
409 + 33489763 = 33490172
433 + 33489739 = 33490172
523 + 33489649 = 33490172

Showing the first eight; more decompositions exist.
