Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503162, here are decompositions:

11 + 31503151 = 31503162
23 + 31503139 = 31503162
43 + 31503119 = 31503162
59 + 31503103 = 31503162
101 + 31503061 = 31503162
109 + 31503053 = 31503162
199 + 31502963 = 31503162
239 + 31502923 = 31503162

Showing the first eight; more decompositions exist.
