Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472420, here are decompositions:

89 + 33472331 = 33472420
197 + 33472223 = 33472420
227 + 33472193 = 33472420
239 + 33472181 = 33472420
257 + 33472163 = 33472420
281 + 33472139 = 33472420
353 + 33472067 = 33472420
431 + 33471989 = 33472420

Showing the first eight; more decompositions exist.
