Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749402, here are decompositions:

59 + 8749343 = 8749402
71 + 8749331 = 8749402
173 + 8749229 = 8749402
239 + 8749163 = 8749402
251 + 8749151 = 8749402
269 + 8749133 = 8749402
281 + 8749121 = 8749402
353 + 8749049 = 8749402

Showing the first eight; more decompositions exist.
