Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690738, here are decompositions:

61 + 8690677 = 8690738
79 + 8690659 = 8690738
127 + 8690611 = 8690738
139 + 8690599 = 8690738
181 + 8690557 = 8690738
367 + 8690371 = 8690738
379 + 8690359 = 8690738
421 + 8690317 = 8690738

Showing the first eight; more decompositions exist.
