Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713388, here are decompositions:

97 + 8713291 = 8713388
127 + 8713261 = 8713388
139 + 8713249 = 8713388
337 + 8713051 = 8713388
379 + 8713009 = 8713388
457 + 8712931 = 8713388
631 + 8712757 = 8713388
661 + 8712727 = 8713388

Showing the first eight; more decompositions exist.
