Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749842, here are decompositions:

5 + 8749837 = 8749842
29 + 8749813 = 8749842
53 + 8749789 = 8749842
71 + 8749771 = 8749842
89 + 8749753 = 8749842
109 + 8749733 = 8749842
173 + 8749669 = 8749842
191 + 8749651 = 8749842

Showing the first eight; more decompositions exist.
