Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515364, here are decompositions:

11 + 31515353 = 31515364
47 + 31515317 = 31515364
53 + 31515311 = 31515364
137 + 31515227 = 31515364
227 + 31515137 = 31515364
317 + 31515047 = 31515364
383 + 31514981 = 31515364
401 + 31514963 = 31515364

Showing the first eight; more decompositions exist.
