Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606030, here are decompositions:

47 + 31605983 = 31606030
59 + 31605971 = 31606030
101 + 31605929 = 31606030
227 + 31605803 = 31606030
251 + 31605779 = 31606030
257 + 31605773 = 31606030
311 + 31605719 = 31606030
317 + 31605713 = 31606030

Showing the first eight; more decompositions exist.
