Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731170, here are decompositions:

17 + 8731153 = 8731170
29 + 8731141 = 8731170
31 + 8731139 = 8731170
59 + 8731111 = 8731170
61 + 8731109 = 8731170
67 + 8731103 = 8731170
73 + 8731097 = 8731170
101 + 8731069 = 8731170

Showing the first eight; more decompositions exist.
