Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503332, here are decompositions:

19 + 31503313 = 31503332
73 + 31503259 = 31503332
103 + 31503229 = 31503332
151 + 31503181 = 31503332
181 + 31503151 = 31503332
193 + 31503139 = 31503332
229 + 31503103 = 31503332
271 + 31503061 = 31503332

Showing the first eight; more decompositions exist.
