Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732028, here are decompositions:

5 + 8732023 = 8732028
37 + 8731991 = 8732028
47 + 8731981 = 8732028
89 + 8731939 = 8732028
127 + 8731901 = 8732028
167 + 8731861 = 8732028
197 + 8731831 = 8732028
211 + 8731817 = 8732028

Showing the first eight; more decompositions exist.
