Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500368, here are decompositions:

7 + 31500361 = 31500368
181 + 31500187 = 31500368
379 + 31499989 = 31500368
607 + 31499761 = 31500368
709 + 31499659 = 31500368
769 + 31499599 = 31500368
877 + 31499491 = 31500368
937 + 31499431 = 31500368

Showing the first eight; more decompositions exist.
