Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691344, here are decompositions:

31 + 8691313 = 8691344
97 + 8691247 = 8691344
157 + 8691187 = 8691344
373 + 8690971 = 8691344
397 + 8690947 = 8691344
523 + 8690821 = 8691344
547 + 8690797 = 8691344
577 + 8690767 = 8691344

Showing the first eight; more decompositions exist.
