Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723338, here are decompositions:

17 + 8723321 = 8723338
257 + 8723081 = 8723338
347 + 8722991 = 8723338
389 + 8722949 = 8723338
461 + 8722877 = 8723338
479 + 8722859 = 8723338
509 + 8722829 = 8723338
599 + 8722739 = 8723338

Showing the first eight; more decompositions exist.
