Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661552, here are decompositions:

23 + 8661529 = 8661552
43 + 8661509 = 8661552
61 + 8661491 = 8661552
73 + 8661479 = 8661552
83 + 8661469 = 8661552
113 + 8661439 = 8661552
139 + 8661413 = 8661552
199 + 8661353 = 8661552

Showing the first eight; more decompositions exist.
