Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742310, here are decompositions:

47 + 8742263 = 8742310
113 + 8742197 = 8742310
149 + 8742161 = 8742310
233 + 8742077 = 8742310
251 + 8742059 = 8742310
359 + 8741951 = 8742310
443 + 8741867 = 8742310
449 + 8741861 = 8742310

Showing the first eight; more decompositions exist.
