Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563872, here are decompositions:

71 + 33563801 = 33563872
101 + 33563771 = 33563872
131 + 33563741 = 33563872
263 + 33563609 = 33563872
401 + 33563471 = 33563872
431 + 33563441 = 33563872
491 + 33563381 = 33563872
599 + 33563273 = 33563872

Showing the first eight; more decompositions exist.
