Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628488, here are decompositions:

7 + 8628481 = 8628488
67 + 8628421 = 8628488
139 + 8628349 = 8628488
307 + 8628181 = 8628488
331 + 8628157 = 8628488
367 + 8628121 = 8628488
439 + 8628049 = 8628488
457 + 8628031 = 8628488

Showing the first eight; more decompositions exist.
