Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681418, here are decompositions:

17 + 8681401 = 8681418
41 + 8681377 = 8681418
59 + 8681359 = 8681418
61 + 8681357 = 8681418
101 + 8681317 = 8681418
107 + 8681311 = 8681418
127 + 8681291 = 8681418
131 + 8681287 = 8681418

Showing the first eight; more decompositions exist.
