Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537972, here are decompositions:

11 + 33537961 = 33537972
31 + 33537941 = 33537972
53 + 33537919 = 33537972
73 + 33537899 = 33537972
109 + 33537863 = 33537972
163 + 33537809 = 33537972
263 + 33537709 = 33537972
271 + 33537701 = 33537972

Showing the first eight; more decompositions exist.
