Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749140, here are decompositions:

7 + 8749133 = 8749140
13 + 8749127 = 8749140
19 + 8749121 = 8749140
53 + 8749087 = 8749140
139 + 8749001 = 8749140
149 + 8748991 = 8749140
151 + 8748989 = 8749140
167 + 8748973 = 8749140

Showing the first eight; more decompositions exist.
