Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503416, here are decompositions:

37 + 31503379 = 31503416
73 + 31503343 = 31503416
79 + 31503337 = 31503416
103 + 31503313 = 31503416
157 + 31503259 = 31503416
199 + 31503217 = 31503416
277 + 31503139 = 31503416
313 + 31503103 = 31503416

Showing the first eight; more decompositions exist.
