Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688746, here are decompositions:

7 + 8688739 = 8688746
43 + 8688703 = 8688746
139 + 8688607 = 8688746
163 + 8688583 = 8688746
193 + 8688553 = 8688746
277 + 8688469 = 8688746
337 + 8688409 = 8688746
349 + 8688397 = 8688746

Showing the first eight; more decompositions exist.
