Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737842, here are decompositions:

13 + 8737829 = 8737842
41 + 8737801 = 8737842
53 + 8737789 = 8737842
59 + 8737783 = 8737842
79 + 8737763 = 8737842
101 + 8737741 = 8737842
149 + 8737693 = 8737842
173 + 8737669 = 8737842

Showing the first eight; more decompositions exist.
