Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749210, here are decompositions:

3 + 8749207 = 8749210
11 + 8749199 = 8749210
47 + 8749163 = 8749210
59 + 8749151 = 8749210
83 + 8749127 = 8749210
89 + 8749121 = 8749210
191 + 8749019 = 8749210
257 + 8748953 = 8749210

Showing the first eight; more decompositions exist.
