Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503232, here are decompositions:

3 + 31503229 = 31503232
23 + 31503209 = 31503232
29 + 31503203 = 31503232
53 + 31503179 = 31503232
113 + 31503119 = 31503232
179 + 31503053 = 31503232
239 + 31502993 = 31503232
269 + 31502963 = 31503232

Showing the first eight; more decompositions exist.
