Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723810, here are decompositions:

3 + 8723807 = 8723810
79 + 8723731 = 8723810
103 + 8723707 = 8723810
157 + 8723653 = 8723810
241 + 8723569 = 8723810
313 + 8723497 = 8723810
331 + 8723479 = 8723810
373 + 8723437 = 8723810

Showing the first eight; more decompositions exist.
