Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462080, here are decompositions:

11 + 31462069 = 31462080
59 + 31462021 = 31462080
73 + 31462007 = 31462080
101 + 31461979 = 31462080
103 + 31461977 = 31462080
131 + 31461949 = 31462080
137 + 31461943 = 31462080
157 + 31461923 = 31462080

Showing the first eight; more decompositions exist.
