Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643342, here are decompositions:

5 + 8643337 = 8643342
61 + 8643281 = 8643342
131 + 8643211 = 8643342
193 + 8643149 = 8643342
199 + 8643143 = 8643342
233 + 8643109 = 8643342
251 + 8643091 = 8643342
283 + 8643059 = 8643342

Showing the first eight; more decompositions exist.
