Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500062, here are decompositions:

73 + 31499989 = 31500062
163 + 31499899 = 31500062
199 + 31499863 = 31500062
229 + 31499833 = 31500062
331 + 31499731 = 31500062
463 + 31499599 = 31500062
571 + 31499491 = 31500062
631 + 31499431 = 31500062

Showing the first eight; more decompositions exist.
