Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485926, here are decompositions:

37 + 31485889 = 31485926
103 + 31485823 = 31485926
127 + 31485799 = 31485926
499 + 31485427 = 31485926
547 + 31485379 = 31485926
607 + 31485319 = 31485926
613 + 31485313 = 31485926
643 + 31485283 = 31485926

Showing the first eight; more decompositions exist.
