Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575694, here are decompositions:

23 + 31575671 = 31575694
41 + 31575653 = 31575694
53 + 31575641 = 31575694
83 + 31575611 = 31575694
131 + 31575563 = 31575694
173 + 31575521 = 31575694
257 + 31575437 = 31575694
317 + 31575377 = 31575694

Showing the first eight; more decompositions exist.
