Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723748, here are decompositions:

17 + 8723731 = 8723748
41 + 8723707 = 8723748
71 + 8723677 = 8723748
109 + 8723639 = 8723748
139 + 8723609 = 8723748
179 + 8723569 = 8723748
197 + 8723551 = 8723748
227 + 8723521 = 8723748

Showing the first eight; more decompositions exist.
