Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503256, here are decompositions:

47 + 31503209 = 31503256
53 + 31503203 = 31503256
89 + 31503167 = 31503256
137 + 31503119 = 31503256
149 + 31503107 = 31503256
263 + 31502993 = 31503256
293 + 31502963 = 31503256
359 + 31502897 = 31503256

Showing the first eight; more decompositions exist.
