Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627914, here are decompositions:

11 + 31627903 = 31627914
53 + 31627861 = 31627914
103 + 31627811 = 31627914
113 + 31627801 = 31627914
151 + 31627763 = 31627914
163 + 31627751 = 31627914
193 + 31627721 = 31627914
313 + 31627601 = 31627914

Showing the first eight; more decompositions exist.
