Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576848, here are decompositions:

5 + 31576843 = 31576848
71 + 31576777 = 31576848
89 + 31576759 = 31576848
97 + 31576751 = 31576848
109 + 31576739 = 31576848
139 + 31576709 = 31576848
167 + 31576681 = 31576848
229 + 31576619 = 31576848

Showing the first eight; more decompositions exist.
