Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643952, here are decompositions:

11 + 8643941 = 8643952
29 + 8643923 = 8643952
59 + 8643893 = 8643952
101 + 8643851 = 8643952
113 + 8643839 = 8643952
131 + 8643821 = 8643952
173 + 8643779 = 8643952
281 + 8643671 = 8643952

Showing the first eight; more decompositions exist.
