Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527130, here are decompositions:

23 + 31527107 = 31527130
53 + 31527077 = 31527130
83 + 31527047 = 31527130
113 + 31527017 = 31527130
191 + 31526939 = 31527130
227 + 31526903 = 31527130
251 + 31526879 = 31527130
311 + 31526819 = 31527130

Showing the first eight; more decompositions exist.
