Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690538, here are decompositions:

7 + 8690531 = 8690538
61 + 8690477 = 8690538
127 + 8690411 = 8690538
139 + 8690399 = 8690538
151 + 8690387 = 8690538
167 + 8690371 = 8690538
179 + 8690359 = 8690538
271 + 8690267 = 8690538

Showing the first eight; more decompositions exist.
