Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33492978, here are decompositions:

7 + 33492971 = 33492978
61 + 33492917 = 33492978
89 + 33492889 = 33492978
107 + 33492871 = 33492978
131 + 33492847 = 33492978
251 + 33492727 = 33492978
331 + 33492647 = 33492978
347 + 33492631 = 33492978

Showing the first eight; more decompositions exist.
