Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637992, here are decompositions:

19 + 8637973 = 8637992
163 + 8637829 = 8637992
373 + 8637619 = 8637992
499 + 8637493 = 8637992
541 + 8637451 = 8637992
613 + 8637379 = 8637992
619 + 8637373 = 8637992
673 + 8637319 = 8637992

Showing the first eight; more decompositions exist.
