Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545098, here are decompositions:

7 + 31545091 = 31545098
31 + 31545067 = 31545098
37 + 31545061 = 31545098
97 + 31545001 = 31545098
157 + 31544941 = 31545098
199 + 31544899 = 31545098
241 + 31544857 = 31545098
271 + 31544827 = 31545098

Showing the first eight; more decompositions exist.
