Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503276, here are decompositions:

17 + 31503259 = 31503276
47 + 31503229 = 31503276
59 + 31503217 = 31503276
67 + 31503209 = 31503276
73 + 31503203 = 31503276
97 + 31503179 = 31503276
109 + 31503167 = 31503276
137 + 31503139 = 31503276

Showing the first eight; more decompositions exist.
