Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732120, here are decompositions:

3 + 8732117 = 8732120
73 + 8732047 = 8732120
97 + 8732023 = 8732120
127 + 8731993 = 8732120
139 + 8731981 = 8732120
181 + 8731939 = 8732120
337 + 8731783 = 8732120
409 + 8731711 = 8732120

Showing the first eight; more decompositions exist.
