Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749146, here are decompositions:

5 + 8749141 = 8749146
13 + 8749133 = 8749146
19 + 8749127 = 8749146
59 + 8749087 = 8749146
97 + 8749049 = 8749146
127 + 8749019 = 8749146
139 + 8749007 = 8749146
157 + 8748989 = 8749146

Showing the first eight; more decompositions exist.
