Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723430, here are decompositions:

7 + 8723423 = 8723430
11 + 8723419 = 8723430
31 + 8723399 = 8723430
43 + 8723387 = 8723430
71 + 8723359 = 8723430
83 + 8723347 = 8723430
109 + 8723321 = 8723430
113 + 8723317 = 8723430

Showing the first eight; more decompositions exist.
