Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654380, here are decompositions:

23 + 8654357 = 8654380
29 + 8654351 = 8654380
41 + 8654339 = 8654380
47 + 8654333 = 8654380
131 + 8654249 = 8654380
149 + 8654231 = 8654380
179 + 8654201 = 8654380
197 + 8654183 = 8654380

Showing the first eight; more decompositions exist.
