Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661124, here are decompositions:

5 + 8661119 = 8661124
137 + 8660987 = 8661124
191 + 8660933 = 8661124
233 + 8660891 = 8661124
383 + 8660741 = 8661124
401 + 8660723 = 8661124
431 + 8660693 = 8661124
443 + 8660681 = 8661124

Showing the first eight; more decompositions exist.
