Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731956, here are decompositions:

5 + 8731951 = 8731956
17 + 8731939 = 8731956
19 + 8731937 = 8731956
43 + 8731913 = 8731956
83 + 8731873 = 8731956
89 + 8731867 = 8731956
97 + 8731859 = 8731956
137 + 8731819 = 8731956

Showing the first eight; more decompositions exist.
