Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661112, here are decompositions:

23 + 8661089 = 8661112
179 + 8660933 = 8661112
191 + 8660921 = 8661112
293 + 8660819 = 8661112
359 + 8660753 = 8661112
389 + 8660723 = 8661112
419 + 8660693 = 8661112
431 + 8660681 = 8661112

Showing the first eight; more decompositions exist.
