Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603978, here are decompositions:

7 + 33603971 = 33603978
29 + 33603949 = 33603978
131 + 33603847 = 33603978
139 + 33603839 = 33603978
181 + 33603797 = 33603978
211 + 33603767 = 33603978
227 + 33603751 = 33603978
271 + 33603707 = 33603978

Showing the first eight; more decompositions exist.
