Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523618, here are decompositions:

17 + 33523601 = 33523618
41 + 33523577 = 33523618
239 + 33523379 = 33523618
347 + 33523271 = 33523618
389 + 33523229 = 33523618
449 + 33523169 = 33523618
509 + 33523109 = 33523618
659 + 33522959 = 33523618

Showing the first eight; more decompositions exist.
