Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614988, here are decompositions:

47 + 31614941 = 31614988
59 + 31614929 = 31614988
89 + 31614899 = 31614988
107 + 31614881 = 31614988
137 + 31614851 = 31614988
149 + 31614839 = 31614988
191 + 31614797 = 31614988
281 + 31614707 = 31614988

Showing the first eight; more decompositions exist.
