Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606304, here are decompositions:

7 + 31606297 = 31606304
43 + 31606261 = 31606304
523 + 31605781 = 31606304
547 + 31605757 = 31606304
577 + 31605727 = 31606304
607 + 31605697 = 31606304
727 + 31605577 = 31606304
733 + 31605571 = 31606304

Showing the first eight; more decompositions exist.
