Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503454, here are decompositions:

11 + 31503443 = 31503454
113 + 31503341 = 31503454
131 + 31503323 = 31503454
251 + 31503203 = 31503454
347 + 31503107 = 31503454
401 + 31503053 = 31503454
461 + 31502993 = 31503454
491 + 31502963 = 31503454

Showing the first eight; more decompositions exist.
