Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723832, here are decompositions:

11 + 8723821 = 8723832
43 + 8723789 = 8723832
101 + 8723731 = 8723832
179 + 8723653 = 8723832
193 + 8723639 = 8723832
223 + 8723609 = 8723832
239 + 8723593 = 8723832
263 + 8723569 = 8723832

Showing the first eight; more decompositions exist.
