Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690884, here are decompositions:

17 + 8690867 = 8690884
71 + 8690813 = 8690884
101 + 8690783 = 8690884
281 + 8690603 = 8690884
317 + 8690567 = 8690884
353 + 8690531 = 8690884
431 + 8690453 = 8690884
593 + 8690291 = 8690884

Showing the first eight; more decompositions exist.
