Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742562, here are decompositions:

11 + 8742551 = 8742562
113 + 8742449 = 8742562
401 + 8742161 = 8742562
503 + 8742059 = 8742562
701 + 8741861 = 8742562
761 + 8741801 = 8742562
809 + 8741753 = 8742562
821 + 8741741 = 8742562

Showing the first eight; more decompositions exist.
