Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690920, here are decompositions:

3 + 8690917 = 8690920
53 + 8690867 = 8690920
107 + 8690813 = 8690920
131 + 8690789 = 8690920
137 + 8690783 = 8690920
179 + 8690741 = 8690920
257 + 8690663 = 8690920
281 + 8690639 = 8690920

Showing the first eight; more decompositions exist.
