Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723826, here are decompositions:

5 + 8723821 = 8723826
19 + 8723807 = 8723826
37 + 8723789 = 8723826
149 + 8723677 = 8723826
173 + 8723653 = 8723826
233 + 8723593 = 8723826
257 + 8723569 = 8723826
347 + 8723479 = 8723826

Showing the first eight; more decompositions exist.
