Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742582, here are decompositions:

5 + 8742577 = 8742582
11 + 8742571 = 8742582
31 + 8742551 = 8742582
41 + 8742541 = 8742582
53 + 8742529 = 8742582
71 + 8742511 = 8742582
83 + 8742499 = 8742582
89 + 8742493 = 8742582

Showing the first eight; more decompositions exist.
