Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734842, here are decompositions:

19 + 8734823 = 8734842
23 + 8734819 = 8734842
41 + 8734801 = 8734842
73 + 8734769 = 8734842
101 + 8734741 = 8734842
113 + 8734729 = 8734842
199 + 8734643 = 8734842
229 + 8734613 = 8734842

Showing the first eight; more decompositions exist.
