Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638376, here are decompositions:

3 + 8638373 = 8638376
37 + 8638339 = 8638376
139 + 8638237 = 8638376
157 + 8638219 = 8638376
163 + 8638213 = 8638376
193 + 8638183 = 8638376
337 + 8638039 = 8638376
433 + 8637943 = 8638376

Showing the first eight; more decompositions exist.
