Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690842, here are decompositions:

29 + 8690813 = 8690842
53 + 8690789 = 8690842
59 + 8690783 = 8690842
101 + 8690741 = 8690842
179 + 8690663 = 8690842
239 + 8690603 = 8690842
311 + 8690531 = 8690842
353 + 8690489 = 8690842

Showing the first eight; more decompositions exist.
