Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490142, here are decompositions:

139 + 33490003 = 33490142
163 + 33489979 = 33490142
181 + 33489961 = 33490142
199 + 33489943 = 33490142
211 + 33489931 = 33490142
241 + 33489901 = 33490142
271 + 33489871 = 33490142
313 + 33489829 = 33490142

Showing the first eight; more decompositions exist.
