Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503306, here are decompositions:

47 + 31503259 = 31503306
89 + 31503217 = 31503306
97 + 31503209 = 31503306
103 + 31503203 = 31503306
127 + 31503179 = 31503306
139 + 31503167 = 31503306
167 + 31503139 = 31503306
199 + 31503107 = 31503306

Showing the first eight; more decompositions exist.
