Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723802, here are decompositions:

13 + 8723789 = 8723802
71 + 8723731 = 8723802
149 + 8723653 = 8723802
163 + 8723639 = 8723802
193 + 8723609 = 8723802
233 + 8723569 = 8723802
251 + 8723551 = 8723802
271 + 8723531 = 8723802

Showing the first eight; more decompositions exist.
