Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618286, here are decompositions:

13 + 8618273 = 8618286
29 + 8618257 = 8618286
43 + 8618243 = 8618286
73 + 8618213 = 8618286
113 + 8618173 = 8618286
137 + 8618149 = 8618286
139 + 8618147 = 8618286
167 + 8618119 = 8618286

Showing the first eight; more decompositions exist.
