Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745132, here are decompositions:

13 + 8745119 = 8745132
31 + 8745101 = 8745132
61 + 8745071 = 8745132
101 + 8745031 = 8745132
113 + 8745019 = 8745132
163 + 8744969 = 8745132
181 + 8744951 = 8745132
191 + 8744941 = 8745132

Showing the first eight; more decompositions exist.
