Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503094, here are decompositions:

41 + 31503053 = 31503094
101 + 31502993 = 31503094
131 + 31502963 = 31503094
167 + 31502927 = 31503094
197 + 31502897 = 31503094
317 + 31502777 = 31503094
653 + 31502441 = 31503094
761 + 31502333 = 31503094

Showing the first eight; more decompositions exist.
