Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621356, here are decompositions:

17 + 8621339 = 8621356
47 + 8621309 = 8621356
113 + 8621243 = 8621356
167 + 8621189 = 8621356
173 + 8621183 = 8621356
269 + 8621087 = 8621356
347 + 8621009 = 8621356
383 + 8620973 = 8621356

Showing the first eight; more decompositions exist.
