Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723888, here are decompositions:

37 + 8723851 = 8723888
67 + 8723821 = 8723888
157 + 8723731 = 8723888
181 + 8723707 = 8723888
211 + 8723677 = 8723888
337 + 8723551 = 8723888
367 + 8723521 = 8723888
409 + 8723479 = 8723888

Showing the first eight; more decompositions exist.
