Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533582, here are decompositions:

11 + 31533571 = 31533582
19 + 31533563 = 31533582
71 + 31533511 = 31533582
83 + 31533499 = 31533582
131 + 31533451 = 31533582
151 + 31533431 = 31533582
173 + 31533409 = 31533582
193 + 31533389 = 31533582

Showing the first eight; more decompositions exist.
