Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529198, here are decompositions:

31 + 31529167 = 31529198
109 + 31529089 = 31529198
229 + 31528969 = 31529198
367 + 31528831 = 31529198
397 + 31528801 = 31529198
457 + 31528741 = 31529198
577 + 31528621 = 31529198
619 + 31528579 = 31529198

Showing the first eight; more decompositions exist.
