Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514526, here are decompositions:

13 + 31514513 = 31514526
47 + 31514479 = 31514526
53 + 31514473 = 31514526
97 + 31514429 = 31514526
103 + 31514423 = 31514526
107 + 31514419 = 31514526
229 + 31514297 = 31514526
367 + 31514159 = 31514526

Showing the first eight; more decompositions exist.
