Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731344, here are decompositions:

5 + 8731339 = 8731344
23 + 8731321 = 8731344
31 + 8731313 = 8731344
43 + 8731301 = 8731344
67 + 8731277 = 8731344
113 + 8731231 = 8731344
131 + 8731213 = 8731344
157 + 8731187 = 8731344

Showing the first eight; more decompositions exist.
