Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742352, here are decompositions:

5 + 8742347 = 8742352
89 + 8742263 = 8742352
191 + 8742161 = 8742352
293 + 8742059 = 8742352
401 + 8741951 = 8742352
419 + 8741933 = 8742352
491 + 8741861 = 8742352
599 + 8741753 = 8742352

Showing the first eight; more decompositions exist.
