Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491272, here are decompositions:

5 + 33491267 = 33491272
11 + 33491261 = 33491272
131 + 33491141 = 33491272
173 + 33491099 = 33491272
281 + 33490991 = 33491272
383 + 33490889 = 33491272
431 + 33490841 = 33491272
491 + 33490781 = 33491272

Showing the first eight; more decompositions exist.
