Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681624, here are decompositions:

37 + 8681587 = 8681624
151 + 8681473 = 8681624
157 + 8681467 = 8681624
223 + 8681401 = 8681624
283 + 8681341 = 8681624
307 + 8681317 = 8681624
313 + 8681311 = 8681624
337 + 8681287 = 8681624

Showing the first eight; more decompositions exist.
