Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742882, here are decompositions:

61 + 8742821 = 8742882
103 + 8742779 = 8742882
193 + 8742689 = 8742882
229 + 8742653 = 8742882
311 + 8742571 = 8742882
331 + 8742551 = 8742882
353 + 8742529 = 8742882
383 + 8742499 = 8742882

Showing the first eight; more decompositions exist.
