Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689470, here are decompositions:

7 + 8689463 = 8689470
17 + 8689453 = 8689470
19 + 8689451 = 8689470
37 + 8689433 = 8689470
71 + 8689399 = 8689470
149 + 8689321 = 8689470
151 + 8689319 = 8689470
191 + 8689279 = 8689470

Showing the first eight; more decompositions exist.
