Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661152, here are decompositions:

103 + 8661049 = 8661152
109 + 8661043 = 8661152
151 + 8661001 = 8661152
223 + 8660929 = 8661152
463 + 8660689 = 8661152
499 + 8660653 = 8661152
541 + 8660611 = 8661152
613 + 8660539 = 8661152

Showing the first eight; more decompositions exist.
