Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723806, here are decompositions:

17 + 8723789 = 8723806
167 + 8723639 = 8723806
197 + 8723609 = 8723806
347 + 8723459 = 8723806
383 + 8723423 = 8723806
419 + 8723387 = 8723806
503 + 8723303 = 8723806
563 + 8723243 = 8723806

Showing the first eight; more decompositions exist.
