Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612100, here are decompositions:

11 + 8612089 = 8612100
41 + 8612059 = 8612100
43 + 8612057 = 8612100
61 + 8612039 = 8612100
67 + 8612033 = 8612100
89 + 8612011 = 8612100
109 + 8611991 = 8612100
113 + 8611987 = 8612100

Showing the first eight; more decompositions exist.
