Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531324, here are decompositions:

23 + 31531301 = 31531324
53 + 31531271 = 31531324
107 + 31531217 = 31531324
347 + 31530977 = 31531324
431 + 31530893 = 31531324
491 + 31530833 = 31531324
641 + 31530683 = 31531324
683 + 31530641 = 31531324

Showing the first eight; more decompositions exist.
