Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681426, here are decompositions:

67 + 8681359 = 8681426
109 + 8681317 = 8681426
139 + 8681287 = 8681426
163 + 8681263 = 8681426
337 + 8681089 = 8681426
349 + 8681077 = 8681426
367 + 8681059 = 8681426
379 + 8681047 = 8681426

Showing the first eight; more decompositions exist.
