Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732646, here are decompositions:

5 + 8732641 = 8732646
7 + 8732639 = 8732646
19 + 8732627 = 8732646
47 + 8732599 = 8732646
53 + 8732593 = 8732646
73 + 8732573 = 8732646
157 + 8732489 = 8732646
173 + 8732473 = 8732646

Showing the first eight; more decompositions exist.
