Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497834, here are decompositions:

7 + 31497827 = 31497834
31 + 31497803 = 31497834
37 + 31497797 = 31497834
61 + 31497773 = 31497834
83 + 31497751 = 31497834
97 + 31497737 = 31497834
107 + 31497727 = 31497834
113 + 31497721 = 31497834

Showing the first eight; more decompositions exist.
