Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503494, here are decompositions:

151 + 31503343 = 31503494
157 + 31503337 = 31503494
163 + 31503331 = 31503494
181 + 31503313 = 31503494
277 + 31503217 = 31503494
313 + 31503181 = 31503494
433 + 31503061 = 31503494
541 + 31502953 = 31503494

Showing the first eight; more decompositions exist.
