Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503426, here are decompositions:

47 + 31503379 = 31503426
83 + 31503343 = 31503426
89 + 31503337 = 31503426
103 + 31503323 = 31503426
113 + 31503313 = 31503426
167 + 31503259 = 31503426
197 + 31503229 = 31503426
223 + 31503203 = 31503426

Showing the first eight; more decompositions exist.
