Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731538, here are decompositions:

7 + 8731531 = 8731538
37 + 8731501 = 8731538
61 + 8731477 = 8731538
157 + 8731381 = 8731538
199 + 8731339 = 8731538
229 + 8731309 = 8731538
307 + 8731231 = 8731538
337 + 8731201 = 8731538

Showing the first eight; more decompositions exist.
