Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723846, here are decompositions:

13 + 8723833 = 8723846
139 + 8723707 = 8723846
193 + 8723653 = 8723846
277 + 8723569 = 8723846
349 + 8723497 = 8723846
367 + 8723479 = 8723846
409 + 8723437 = 8723846
487 + 8723359 = 8723846

Showing the first eight; more decompositions exist.
