Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621376, here are decompositions:

37 + 8621339 = 8621376
67 + 8621309 = 8621376
139 + 8621237 = 8621376
163 + 8621213 = 8621376
167 + 8621209 = 8621376
193 + 8621183 = 8621376
223 + 8621153 = 8621376
229 + 8621147 = 8621376

Showing the first eight; more decompositions exist.
