Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723488, here are decompositions:

5 + 8723483 = 8723488
29 + 8723459 = 8723488
47 + 8723441 = 8723488
89 + 8723399 = 8723488
101 + 8723387 = 8723488
167 + 8723321 = 8723488
647 + 8722841 = 8723488
659 + 8722829 = 8723488

Showing the first eight; more decompositions exist.
