Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731626, here are decompositions:

17 + 8731609 = 8731626
19 + 8731607 = 8731626
47 + 8731579 = 8731626
97 + 8731529 = 8731626
149 + 8731477 = 8731626
179 + 8731447 = 8731626
193 + 8731433 = 8731626
199 + 8731427 = 8731626

Showing the first eight; more decompositions exist.
