Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723662, here are decompositions:

23 + 8723639 = 8723662
53 + 8723609 = 8723662
131 + 8723531 = 8723662
179 + 8723483 = 8723662
239 + 8723423 = 8723662
263 + 8723399 = 8723662
359 + 8723303 = 8723662
419 + 8723243 = 8723662

Showing the first eight; more decompositions exist.
