Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497228, here are decompositions:

157 + 33497071 = 33497228
181 + 33497047 = 33497228
199 + 33497029 = 33497228
307 + 33496921 = 33497228
367 + 33496861 = 33497228
379 + 33496849 = 33497228
577 + 33496651 = 33497228
601 + 33496627 = 33497228

Showing the first eight; more decompositions exist.
