Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503318, here are decompositions:

5 + 31503313 = 31503318
59 + 31503259 = 31503318
89 + 31503229 = 31503318
101 + 31503217 = 31503318
109 + 31503209 = 31503318
137 + 31503181 = 31503318
139 + 31503179 = 31503318
151 + 31503167 = 31503318

Showing the first eight; more decompositions exist.
