Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690558, here are decompositions:

7 + 8690551 = 8690558
181 + 8690377 = 8690558
199 + 8690359 = 8690558
241 + 8690317 = 8690558
337 + 8690221 = 8690558
367 + 8690191 = 8690558
439 + 8690119 = 8690558
571 + 8689987 = 8690558

Showing the first eight; more decompositions exist.
