Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618202, here are decompositions:

29 + 8618173 = 8618202
53 + 8618149 = 8618202
71 + 8618131 = 8618202
83 + 8618119 = 8618202
113 + 8618089 = 8618202
139 + 8618063 = 8618202
181 + 8618021 = 8618202
211 + 8617991 = 8618202

Showing the first eight; more decompositions exist.
