Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732172, here are decompositions:

13 + 8732159 = 8732172
79 + 8732093 = 8732172
101 + 8732071 = 8732172
149 + 8732023 = 8732172
179 + 8731993 = 8732172
181 + 8731991 = 8732172
191 + 8731981 = 8732172
193 + 8731979 = 8732172

Showing the first eight; more decompositions exist.
