Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742960, here are decompositions:

19 + 8742941 = 8742960
29 + 8742931 = 8742960
41 + 8742919 = 8742960
43 + 8742917 = 8742960
73 + 8742887 = 8742960
103 + 8742857 = 8742960
113 + 8742847 = 8742960
139 + 8742821 = 8742960

Showing the first eight; more decompositions exist.
