Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749338, here are decompositions:

7 + 8749331 = 8749338
29 + 8749309 = 8749338
109 + 8749229 = 8749338
131 + 8749207 = 8749338
139 + 8749199 = 8749338
197 + 8749141 = 8749338
211 + 8749127 = 8749338
251 + 8749087 = 8749338

Showing the first eight; more decompositions exist.
