Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550092, here are decompositions:

29 + 31550063 = 31550092
71 + 31550021 = 31550092
113 + 31549979 = 31550092
173 + 31549919 = 31550092
263 + 31549829 = 31550092
293 + 31549799 = 31550092
311 + 31549781 = 31550092
359 + 31549733 = 31550092

Showing the first eight; more decompositions exist.
