Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732100, here are decompositions:

7 + 8732093 = 8732100
19 + 8732081 = 8732100
29 + 8732071 = 8732100
53 + 8732047 = 8732100
71 + 8732029 = 8732100
73 + 8732027 = 8732100
107 + 8731993 = 8732100
109 + 8731991 = 8732100

Showing the first eight; more decompositions exist.
