Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503366, here are decompositions:

5 + 31503361 = 31503366
23 + 31503343 = 31503366
29 + 31503337 = 31503366
43 + 31503323 = 31503366
53 + 31503313 = 31503366
107 + 31503259 = 31503366
137 + 31503229 = 31503366
149 + 31503217 = 31503366

Showing the first eight; more decompositions exist.
