Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723426, here are decompositions:

3 + 8723423 = 8723426
7 + 8723419 = 8723426
67 + 8723359 = 8723426
73 + 8723353 = 8723426
79 + 8723347 = 8723426
109 + 8723317 = 8723426
223 + 8723203 = 8723426
277 + 8723149 = 8723426

Showing the first eight; more decompositions exist.
