Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497566, here are decompositions:

7 + 31497559 = 31497566
19 + 31497547 = 31497566
43 + 31497523 = 31497566
97 + 31497469 = 31497566
103 + 31497463 = 31497566
157 + 31497409 = 31497566
229 + 31497337 = 31497566
283 + 31497283 = 31497566

Showing the first eight; more decompositions exist.
