Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761626, here are decompositions:

7 + 8761619 = 8761626
79 + 8761547 = 8761626
89 + 8761537 = 8761626
109 + 8761517 = 8761626
157 + 8761469 = 8761626
163 + 8761463 = 8761626
173 + 8761453 = 8761626
193 + 8761433 = 8761626

Showing the first eight; more decompositions exist.
