Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500134, here are decompositions:

241 + 31499893 = 31500134
271 + 31499863 = 31500134
331 + 31499803 = 31500134
373 + 31499761 = 31500134
541 + 31499593 = 31500134
643 + 31499491 = 31500134
727 + 31499407 = 31500134
733 + 31499401 = 31500134

Showing the first eight; more decompositions exist.
