Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533722, here are decompositions:

61 + 31533661 = 31533722
109 + 31533613 = 31533722
151 + 31533571 = 31533722
211 + 31533511 = 31533722
223 + 31533499 = 31533722
271 + 31533451 = 31533722
313 + 31533409 = 31533722
379 + 31533343 = 31533722

Showing the first eight; more decompositions exist.
