Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731962, here are decompositions:

11 + 8731951 = 8731962
23 + 8731939 = 8731962
61 + 8731901 = 8731962
89 + 8731873 = 8731962
101 + 8731861 = 8731962
103 + 8731859 = 8731962
131 + 8731831 = 8731962
179 + 8731783 = 8731962

Showing the first eight; more decompositions exist.
