Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621206, here are decompositions:

5 + 8621201 = 8621206
17 + 8621189 = 8621206
23 + 8621183 = 8621206
53 + 8621153 = 8621206
59 + 8621147 = 8621206
197 + 8621009 = 8621206
233 + 8620973 = 8621206
257 + 8620949 = 8621206

Showing the first eight; more decompositions exist.
