Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731168, here are decompositions:

29 + 8731139 = 8731168
59 + 8731109 = 8731168
71 + 8731097 = 8731168
137 + 8731031 = 8731168
191 + 8730977 = 8731168
239 + 8730929 = 8731168
311 + 8730857 = 8731168
317 + 8730851 = 8731168

Showing the first eight; more decompositions exist.
