Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723422, here are decompositions:

3 + 8723419 = 8723422
23 + 8723399 = 8723422
101 + 8723321 = 8723422
179 + 8723243 = 8723422
359 + 8723063 = 8723422
431 + 8722991 = 8723422
509 + 8722913 = 8723422
563 + 8722859 = 8723422

Showing the first eight; more decompositions exist.
