Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550452, here are decompositions:

5 + 31550447 = 31550452
113 + 31550339 = 31550452
239 + 31550213 = 31550452
251 + 31550201 = 31550452
359 + 31550093 = 31550452
389 + 31550063 = 31550452
431 + 31550021 = 31550452
653 + 31549799 = 31550452

Showing the first eight; more decompositions exist.
