Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732090, here are decompositions:

19 + 8732071 = 8732090
43 + 8732047 = 8732090
61 + 8732029 = 8732090
67 + 8732023 = 8732090
97 + 8731993 = 8732090
109 + 8731981 = 8732090
139 + 8731951 = 8732090
151 + 8731939 = 8732090

Showing the first eight; more decompositions exist.
