Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620100, here are decompositions:

31 + 8620069 = 8620100
37 + 8620063 = 8620100
103 + 8619997 = 8620100
157 + 8619943 = 8620100
163 + 8619937 = 8620100
241 + 8619859 = 8620100
283 + 8619817 = 8620100
439 + 8619661 = 8620100

Showing the first eight; more decompositions exist.
