Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723248, here are decompositions:

5 + 8723243 = 8723248
167 + 8723081 = 8723248
257 + 8722991 = 8723248
389 + 8722859 = 8723248
419 + 8722829 = 8723248
449 + 8722799 = 8723248
491 + 8722757 = 8723248
509 + 8722739 = 8723248

Showing the first eight; more decompositions exist.
