Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634242, here are decompositions:

31 + 8634211 = 8634242
73 + 8634169 = 8634242
79 + 8634163 = 8634242
103 + 8634139 = 8634242
109 + 8634133 = 8634242
193 + 8634049 = 8634242
271 + 8633971 = 8634242
283 + 8633959 = 8634242

Showing the first eight; more decompositions exist.
