Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723554, here are decompositions:

3 + 8723551 = 8723554
23 + 8723531 = 8723554
71 + 8723483 = 8723554
113 + 8723441 = 8723554
131 + 8723423 = 8723554
167 + 8723387 = 8723554
233 + 8723321 = 8723554
251 + 8723303 = 8723554

Showing the first eight; more decompositions exist.
