Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621334, here are decompositions:

53 + 8621281 = 8621334
97 + 8621237 = 8621334
151 + 8621183 = 8621334
181 + 8621153 = 8621334
191 + 8621143 = 8621334
233 + 8621101 = 8621334
251 + 8621083 = 8621334
257 + 8621077 = 8621334

Showing the first eight; more decompositions exist.
