Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485504, here are decompositions:

7 + 31485497 = 31485504
31 + 31485473 = 31485504
73 + 31485431 = 31485504
97 + 31485407 = 31485504
103 + 31485401 = 31485504
107 + 31485397 = 31485504
151 + 31485353 = 31485504
163 + 31485341 = 31485504

Showing the first eight; more decompositions exist.
