Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731636, here are decompositions:

29 + 8731607 = 8731636
107 + 8731529 = 8731636
293 + 8731343 = 8731636
359 + 8731277 = 8731636
449 + 8731187 = 8731636
653 + 8730983 = 8731636
659 + 8730977 = 8731636
743 + 8730893 = 8731636

Showing the first eight; more decompositions exist.
