Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689628, here are decompositions:

19 + 8689609 = 8689628
37 + 8689591 = 8689628
139 + 8689489 = 8689628
229 + 8689399 = 8689628
307 + 8689321 = 8689628
349 + 8689279 = 8689628
379 + 8689249 = 8689628
487 + 8689141 = 8689628

Showing the first eight; more decompositions exist.
