Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618392, here are decompositions:

5 + 8618387 = 8618392
53 + 8618339 = 8618392
149 + 8618243 = 8618392
179 + 8618213 = 8618392
359 + 8618033 = 8618392
401 + 8617991 = 8618392
443 + 8617949 = 8618392
449 + 8617943 = 8618392

Showing the first eight; more decompositions exist.
