Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621554, here are decompositions:

3 + 8621551 = 8621554
101 + 8621453 = 8621554
311 + 8621243 = 8621554
317 + 8621237 = 8621554
353 + 8621201 = 8621554
401 + 8621153 = 8621554
467 + 8621087 = 8621554
503 + 8621051 = 8621554

Showing the first eight; more decompositions exist.
