Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615002, here are decompositions:

59 + 31614943 = 31615002
61 + 31614941 = 31615002
73 + 31614929 = 31615002
103 + 31614899 = 31615002
113 + 31614889 = 31615002
149 + 31614853 = 31615002
151 + 31614851 = 31615002
163 + 31614839 = 31615002

Showing the first eight; more decompositions exist.
