Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681684, here are decompositions:

61 + 8681623 = 8681684
97 + 8681587 = 8681684
181 + 8681503 = 8681684
211 + 8681473 = 8681684
283 + 8681401 = 8681684
307 + 8681377 = 8681684
367 + 8681317 = 8681684
373 + 8681311 = 8681684

Showing the first eight; more decompositions exist.
