Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731386, here are decompositions:

5 + 8731381 = 8731386
17 + 8731369 = 8731386
23 + 8731363 = 8731386
43 + 8731343 = 8731386
47 + 8731339 = 8731386
73 + 8731313 = 8731386
109 + 8731277 = 8731386
137 + 8731249 = 8731386

Showing the first eight; more decompositions exist.
