Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550164, here are decompositions:

11 + 31550153 = 31550164
53 + 31550111 = 31550164
71 + 31550093 = 31550164
101 + 31550063 = 31550164
137 + 31550027 = 31550164
197 + 31549967 = 31550164
383 + 31549781 = 31550164
431 + 31549733 = 31550164

Showing the first eight; more decompositions exist.
