Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572618, here are decompositions:

61 + 33572557 = 33572618
97 + 33572521 = 33572618
241 + 33572377 = 33572618
271 + 33572347 = 33572618
307 + 33572311 = 33572618
367 + 33572251 = 33572618
487 + 33572131 = 33572618
577 + 33572041 = 33572618

Showing the first eight; more decompositions exist.
