Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731350, here are decompositions:

7 + 8731343 = 8731350
11 + 8731339 = 8731350
29 + 8731321 = 8731350
37 + 8731313 = 8731350
41 + 8731309 = 8731350
73 + 8731277 = 8731350
101 + 8731249 = 8731350
137 + 8731213 = 8731350

Showing the first eight; more decompositions exist.
