Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749236, here are decompositions:

7 + 8749229 = 8749236
17 + 8749219 = 8749236
29 + 8749207 = 8749236
37 + 8749199 = 8749236
73 + 8749163 = 8749236
103 + 8749133 = 8749236
109 + 8749127 = 8749236
149 + 8749087 = 8749236

Showing the first eight; more decompositions exist.
