Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722548, here are decompositions:

7 + 8722541 = 8722548
31 + 8722517 = 8722548
71 + 8722477 = 8722548
89 + 8722459 = 8722548
101 + 8722447 = 8722548
139 + 8722409 = 8722548
157 + 8722391 = 8722548
181 + 8722367 = 8722548

Showing the first eight; more decompositions exist.
