Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742574, here are decompositions:

3 + 8742571 = 8742574
23 + 8742551 = 8742574
173 + 8742401 = 8742574
227 + 8742347 = 8742574
257 + 8742317 = 8742574
311 + 8742263 = 8742574
563 + 8742011 = 8742574
587 + 8741987 = 8742574

Showing the first eight; more decompositions exist.
