Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559694, here are decompositions:

7 + 31559687 = 31559694
13 + 31559681 = 31559694
17 + 31559677 = 31559694
41 + 31559653 = 31559694
43 + 31559651 = 31559694
53 + 31559641 = 31559694
71 + 31559623 = 31559694
157 + 31559537 = 31559694

Showing the first eight; more decompositions exist.
