Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723622, here are decompositions:

13 + 8723609 = 8723622
29 + 8723593 = 8723622
53 + 8723569 = 8723622
71 + 8723551 = 8723622
101 + 8723521 = 8723622
139 + 8723483 = 8723622
163 + 8723459 = 8723622
181 + 8723441 = 8723622

Showing the first eight; more decompositions exist.
