Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627126, here are decompositions:

5 + 31627121 = 31627126
53 + 31627073 = 31627126
149 + 31626977 = 31627126
227 + 31626899 = 31627126
233 + 31626893 = 31627126
257 + 31626869 = 31627126
269 + 31626857 = 31627126
359 + 31626767 = 31627126

Showing the first eight; more decompositions exist.
