Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621548, here are decompositions:

71 + 8621477 = 8621548
137 + 8621411 = 8621548
239 + 8621309 = 8621548
311 + 8621237 = 8621548
347 + 8621201 = 8621548
359 + 8621189 = 8621548
401 + 8621147 = 8621548
461 + 8621087 = 8621548

Showing the first eight; more decompositions exist.
