Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749156, here are decompositions:

5 + 8749151 = 8749156
23 + 8749133 = 8749156
29 + 8749127 = 8749156
107 + 8749049 = 8749156
137 + 8749019 = 8749156
149 + 8749007 = 8749156
167 + 8748989 = 8749156
263 + 8748893 = 8749156

Showing the first eight; more decompositions exist.
