Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503174, here are decompositions:

7 + 31503167 = 31503174
23 + 31503151 = 31503174
67 + 31503107 = 31503174
71 + 31503103 = 31503174
113 + 31503061 = 31503174
181 + 31502993 = 31503174
211 + 31502963 = 31503174
233 + 31502941 = 31503174

Showing the first eight; more decompositions exist.
