Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533302, here are decompositions:

43 + 31533259 = 31533302
211 + 31533091 = 31533302
331 + 31532971 = 31533302
379 + 31532923 = 31533302
421 + 31532881 = 31533302
439 + 31532863 = 31533302
643 + 31532659 = 31533302
709 + 31532593 = 31533302

Showing the first eight; more decompositions exist.
