Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503264, here are decompositions:

5 + 31503259 = 31503264
47 + 31503217 = 31503264
61 + 31503203 = 31503264
83 + 31503181 = 31503264
97 + 31503167 = 31503264
113 + 31503151 = 31503264
157 + 31503107 = 31503264
211 + 31503053 = 31503264

Showing the first eight; more decompositions exist.
