Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749342, here are decompositions:

5 + 8749337 = 8749342
11 + 8749331 = 8749342
113 + 8749229 = 8749342
179 + 8749163 = 8749342
191 + 8749151 = 8749342
293 + 8749049 = 8749342
353 + 8748989 = 8749342
389 + 8748953 = 8749342

Showing the first eight; more decompositions exist.
