Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550984, here are decompositions:

7 + 31550977 = 31550984
37 + 31550947 = 31550984
61 + 31550923 = 31550984
151 + 31550833 = 31550984
181 + 31550803 = 31550984
193 + 31550791 = 31550984
313 + 31550671 = 31550984
373 + 31550611 = 31550984

Showing the first eight; more decompositions exist.
