Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745842, here are decompositions:

13 + 8745829 = 8745842
43 + 8745799 = 8745842
139 + 8745703 = 8745842
163 + 8745679 = 8745842
229 + 8745613 = 8745842
271 + 8745571 = 8745842
349 + 8745493 = 8745842
499 + 8745343 = 8745842

Showing the first eight; more decompositions exist.
