Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618342, here are decompositions:

3 + 8618339 = 8618342
13 + 8618329 = 8618342
193 + 8618149 = 8618342
211 + 8618131 = 8618342
223 + 8618119 = 8618342
283 + 8618059 = 8618342
349 + 8617993 = 8618342
409 + 8617933 = 8618342

Showing the first eight; more decompositions exist.
