Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731356, here are decompositions:

13 + 8731343 = 8731356
17 + 8731339 = 8731356
43 + 8731313 = 8731356
47 + 8731309 = 8731356
79 + 8731277 = 8731356
107 + 8731249 = 8731356
317 + 8731039 = 8731356
373 + 8730983 = 8731356

Showing the first eight; more decompositions exist.
