Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626394, here are decompositions:

3 + 8626391 = 8626394
97 + 8626297 = 8626394
151 + 8626243 = 8626394
157 + 8626237 = 8626394
331 + 8626063 = 8626394
397 + 8625997 = 8626394
421 + 8625973 = 8626394
433 + 8625961 = 8626394

Showing the first eight; more decompositions exist.
