Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530068, here are decompositions:

7 + 31530061 = 31530068
67 + 31530001 = 31530068
397 + 31529671 = 31530068
439 + 31529629 = 31530068
547 + 31529521 = 31530068
709 + 31529359 = 31530068
811 + 31529257 = 31530068
919 + 31529149 = 31530068

Showing the first eight; more decompositions exist.
