Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690918, here are decompositions:

97 + 8690821 = 8690918
151 + 8690767 = 8690918
241 + 8690677 = 8690918
307 + 8690611 = 8690918
367 + 8690551 = 8690918
541 + 8690377 = 8690918
547 + 8690371 = 8690918
601 + 8690317 = 8690918

Showing the first eight; more decompositions exist.
