Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749090, here are decompositions:

3 + 8749087 = 8749090
41 + 8749049 = 8749090
71 + 8749019 = 8749090
83 + 8749007 = 8749090
89 + 8749001 = 8749090
101 + 8748989 = 8749090
137 + 8748953 = 8749090
197 + 8748893 = 8749090

Showing the first eight; more decompositions exist.
