Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503498, here are decompositions:

29 + 31503469 = 31503498
137 + 31503361 = 31503498
157 + 31503341 = 31503498
167 + 31503331 = 31503498
239 + 31503259 = 31503498
269 + 31503229 = 31503498
281 + 31503217 = 31503498
317 + 31503181 = 31503498

Showing the first eight; more decompositions exist.
