Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627030, here are decompositions:

3 + 31627027 = 31627030
23 + 31627007 = 31627030
53 + 31626977 = 31627030
131 + 31626899 = 31627030
137 + 31626893 = 31627030
173 + 31626857 = 31627030
191 + 31626839 = 31627030
233 + 31626797 = 31627030

Showing the first eight; more decompositions exist.
