Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743020, here are decompositions:

19 + 8743001 = 8743020
23 + 8742997 = 8743020
43 + 8742977 = 8743020
47 + 8742973 = 8743020
79 + 8742941 = 8743020
89 + 8742931 = 8743020
101 + 8742919 = 8743020
103 + 8742917 = 8743020

Showing the first eight; more decompositions exist.
