Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629242, here are decompositions:

29 + 8629213 = 8629242
43 + 8629199 = 8629242
71 + 8629171 = 8629242
73 + 8629169 = 8629242
101 + 8629141 = 8629242
103 + 8629139 = 8629242
163 + 8629079 = 8629242
179 + 8629063 = 8629242

Showing the first eight; more decompositions exist.
