Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503150, here are decompositions:

11 + 31503139 = 31503150
31 + 31503119 = 31503150
43 + 31503107 = 31503150
47 + 31503103 = 31503150
89 + 31503061 = 31503150
97 + 31503053 = 31503150
157 + 31502993 = 31503150
191 + 31502959 = 31503150

Showing the first eight; more decompositions exist.
