Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749420, here are decompositions:

3 + 8749417 = 8749420
83 + 8749337 = 8749420
89 + 8749331 = 8749420
191 + 8749229 = 8749420
257 + 8749163 = 8749420
269 + 8749151 = 8749420
293 + 8749127 = 8749420
401 + 8749019 = 8749420

Showing the first eight; more decompositions exist.
