Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539972, here are decompositions:

31 + 33539941 = 33539972
79 + 33539893 = 33539972
223 + 33539749 = 33539972
229 + 33539743 = 33539972
409 + 33539563 = 33539972
439 + 33539533 = 33539972
463 + 33539509 = 33539972
541 + 33539431 = 33539972

Showing the first eight; more decompositions exist.
