Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487096, here are decompositions:

97 + 31486999 = 31487096
373 + 31486723 = 31487096
439 + 31486657 = 31487096
457 + 31486639 = 31487096
463 + 31486633 = 31487096
547 + 31486549 = 31487096
643 + 31486453 = 31487096
673 + 31486423 = 31487096

Showing the first eight; more decompositions exist.
