Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723474, here are decompositions:

37 + 8723437 = 8723474
127 + 8723347 = 8723474
157 + 8723317 = 8723474
163 + 8723311 = 8723474
271 + 8723203 = 8723474
283 + 8723191 = 8723474
337 + 8723137 = 8723474
367 + 8723107 = 8723474

Showing the first eight; more decompositions exist.
