Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688612, here are decompositions:

5 + 8688607 = 8688612
11 + 8688601 = 8688612
19 + 8688593 = 8688612
29 + 8688583 = 8688612
41 + 8688571 = 8688612
43 + 8688569 = 8688612
59 + 8688553 = 8688612
61 + 8688551 = 8688612

Showing the first eight; more decompositions exist.
