Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625854, here are decompositions:

5 + 31625849 = 31625854
11 + 31625843 = 31625854
47 + 31625807 = 31625854
101 + 31625753 = 31625854
131 + 31625723 = 31625854
173 + 31625681 = 31625854
251 + 31625603 = 31625854
317 + 31625537 = 31625854

Showing the first eight; more decompositions exist.
