Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690508, here are decompositions:

19 + 8690489 = 8690508
31 + 8690477 = 8690508
97 + 8690411 = 8690508
109 + 8690399 = 8690508
131 + 8690377 = 8690508
137 + 8690371 = 8690508
149 + 8690359 = 8690508
157 + 8690351 = 8690508

Showing the first eight; more decompositions exist.
