Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690564, here are decompositions:

7 + 8690557 = 8690564
13 + 8690551 = 8690564
151 + 8690413 = 8690564
193 + 8690371 = 8690564
271 + 8690293 = 8690564
373 + 8690191 = 8690564
523 + 8690041 = 8690564
577 + 8689987 = 8690564

Showing the first eight; more decompositions exist.
