Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605094, here are decompositions:

23 + 31605071 = 31605094
47 + 31605047 = 31605094
107 + 31604987 = 31605094
347 + 31604747 = 31605094
467 + 31604627 = 31605094
491 + 31604603 = 31605094
593 + 31604501 = 31605094
641 + 31604453 = 31605094

Showing the first eight; more decompositions exist.
