Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485672, here are decompositions:

79 + 33485593 = 33485672
229 + 33485443 = 33485672
331 + 33485341 = 33485672
349 + 33485323 = 33485672
373 + 33485299 = 33485672
421 + 33485251 = 33485672
523 + 33485149 = 33485672
541 + 33485131 = 33485672

Showing the first eight; more decompositions exist.
