Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749408, here are decompositions:

71 + 8749337 = 8749408
179 + 8749229 = 8749408
257 + 8749151 = 8749408
281 + 8749127 = 8749408
359 + 8749049 = 8749408
389 + 8749019 = 8749408
401 + 8749007 = 8749408
419 + 8748989 = 8749408

Showing the first eight; more decompositions exist.
