Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503414, here are decompositions:

53 + 31503361 = 31503414
71 + 31503343 = 31503414
73 + 31503341 = 31503414
83 + 31503331 = 31503414
101 + 31503313 = 31503414
197 + 31503217 = 31503414
211 + 31503203 = 31503414
233 + 31503181 = 31503414

Showing the first eight; more decompositions exist.
