Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475616, here are decompositions:

5 + 31475611 = 31475616
17 + 31475599 = 31475616
19 + 31475597 = 31475616
37 + 31475579 = 31475616
127 + 31475489 = 31475616
157 + 31475459 = 31475616
163 + 31475453 = 31475616
173 + 31475443 = 31475616

Showing the first eight; more decompositions exist.
