Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731368, here are decompositions:

5 + 8731363 = 8731368
29 + 8731339 = 8731368
47 + 8731321 = 8731368
59 + 8731309 = 8731368
67 + 8731301 = 8731368
137 + 8731231 = 8731368
157 + 8731211 = 8731368
167 + 8731201 = 8731368

Showing the first eight; more decompositions exist.
