Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749438, here are decompositions:

17 + 8749421 = 8749438
101 + 8749337 = 8749438
107 + 8749331 = 8749438
239 + 8749199 = 8749438
311 + 8749127 = 8749438
317 + 8749121 = 8749438
389 + 8749049 = 8749438
419 + 8749019 = 8749438

Showing the first eight; more decompositions exist.
