Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499504, here are decompositions:

7 + 31499497 = 31499504
13 + 31499491 = 31499504
37 + 31499467 = 31499504
73 + 31499431 = 31499504
97 + 31499407 = 31499504
103 + 31499401 = 31499504
163 + 31499341 = 31499504
181 + 31499323 = 31499504

Showing the first eight; more decompositions exist.
