Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732138, here are decompositions:

67 + 8732071 = 8732138
109 + 8732029 = 8732138
157 + 8731981 = 8732138
199 + 8731939 = 8732138
271 + 8731867 = 8732138
277 + 8731861 = 8732138
307 + 8731831 = 8732138
439 + 8731699 = 8732138

Showing the first eight; more decompositions exist.
