Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742792, here are decompositions:

5 + 8742787 = 8742792
13 + 8742779 = 8742792
53 + 8742739 = 8742792
103 + 8742689 = 8742792
139 + 8742653 = 8742792
241 + 8742551 = 8742792
251 + 8742541 = 8742792
263 + 8742529 = 8742792

Showing the first eight; more decompositions exist.
