Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500848, here are decompositions:

31 + 31500817 = 31500848
157 + 31500691 = 31500848
199 + 31500649 = 31500848
397 + 31500451 = 31500848
487 + 31500361 = 31500848
661 + 31500187 = 31500848
859 + 31499989 = 31500848
1087 + 31499761 = 31500848

Showing the first eight; more decompositions exist.
