Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621152, here are decompositions:

5 + 8621147 = 8621152
101 + 8621051 = 8621152
179 + 8620973 = 8621152
311 + 8620841 = 8621152
431 + 8620721 = 8621152
461 + 8620691 = 8621152
479 + 8620673 = 8621152
521 + 8620631 = 8621152

Showing the first eight; more decompositions exist.
