Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749138, here are decompositions:

5 + 8749133 = 8749138
11 + 8749127 = 8749138
17 + 8749121 = 8749138
89 + 8749049 = 8749138
131 + 8749007 = 8749138
137 + 8749001 = 8749138
149 + 8748989 = 8749138
257 + 8748881 = 8749138

Showing the first eight; more decompositions exist.
