Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615030, here are decompositions:

17 + 31615013 = 31615030
23 + 31615007 = 31615030
89 + 31614941 = 31615030
101 + 31614929 = 31615030
131 + 31614899 = 31615030
149 + 31614881 = 31615030
179 + 31614851 = 31615030
191 + 31614839 = 31615030

Showing the first eight; more decompositions exist.
