Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749290, here are decompositions:

47 + 8749243 = 8749290
61 + 8749229 = 8749290
71 + 8749219 = 8749290
83 + 8749207 = 8749290
127 + 8749163 = 8749290
139 + 8749151 = 8749290
149 + 8749141 = 8749290
157 + 8749133 = 8749290

Showing the first eight; more decompositions exist.
