Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490040, here are decompositions:

37 + 33490003 = 33490040
61 + 33489979 = 33490040
79 + 33489961 = 33490040
97 + 33489943 = 33490040
109 + 33489931 = 33490040
139 + 33489901 = 33490040
163 + 33489877 = 33490040
211 + 33489829 = 33490040

Showing the first eight; more decompositions exist.
