Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681456, here are decompositions:

79 + 8681377 = 8681456
97 + 8681359 = 8681456
139 + 8681317 = 8681456
193 + 8681263 = 8681456
367 + 8681089 = 8681456
379 + 8681077 = 8681456
397 + 8681059 = 8681456
409 + 8681047 = 8681456

Showing the first eight; more decompositions exist.
