Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529694, here are decompositions:

13 + 31529681 = 31529694
17 + 31529677 = 31529694
23 + 31529671 = 31529694
43 + 31529651 = 31529694
71 + 31529623 = 31529694
101 + 31529593 = 31529694
127 + 31529567 = 31529694
137 + 31529557 = 31529694

Showing the first eight; more decompositions exist.
