Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742346, here are decompositions:

29 + 8742317 = 8742346
83 + 8742263 = 8742346
149 + 8742197 = 8742346
269 + 8742077 = 8742346
359 + 8741987 = 8742346
479 + 8741867 = 8742346
593 + 8741753 = 8742346
647 + 8741699 = 8742346

Showing the first eight; more decompositions exist.
