Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503374, here are decompositions:

13 + 31503361 = 31503374
31 + 31503343 = 31503374
37 + 31503337 = 31503374
43 + 31503331 = 31503374
61 + 31503313 = 31503374
157 + 31503217 = 31503374
193 + 31503181 = 31503374
223 + 31503151 = 31503374

Showing the first eight; more decompositions exist.
