Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681672, here are decompositions:

3 + 8681669 = 8681672
199 + 8681473 = 8681672
271 + 8681401 = 8681672
313 + 8681359 = 8681672
331 + 8681341 = 8681672
409 + 8681263 = 8681672
421 + 8681251 = 8681672
541 + 8681131 = 8681672

Showing the first eight; more decompositions exist.
