Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33546978, here are decompositions:

5 + 33546973 = 33546978
37 + 33546941 = 33546978
61 + 33546917 = 33546978
107 + 33546871 = 33546978
139 + 33546839 = 33546978
149 + 33546829 = 33546978
197 + 33546781 = 33546978
239 + 33546739 = 33546978

Showing the first eight; more decompositions exist.
