Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731950, here are decompositions:

11 + 8731939 = 8731950
13 + 8731937 = 8731950
37 + 8731913 = 8731950
43 + 8731907 = 8731950
83 + 8731867 = 8731950
89 + 8731861 = 8731950
131 + 8731819 = 8731950
163 + 8731787 = 8731950

Showing the first eight; more decompositions exist.
