Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689488, here are decompositions:

7 + 8689481 = 8689488
37 + 8689451 = 8689488
89 + 8689399 = 8689488
139 + 8689349 = 8689488
167 + 8689321 = 8689488
179 + 8689309 = 8689488
229 + 8689259 = 8689488
239 + 8689249 = 8689488

Showing the first eight; more decompositions exist.
