Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619100, here are decompositions:

3 + 8619097 = 8619100
23 + 8619077 = 8619100
29 + 8619071 = 8619100
41 + 8619059 = 8619100
47 + 8619053 = 8619100
59 + 8619041 = 8619100
101 + 8618999 = 8619100
167 + 8618933 = 8619100

Showing the first eight; more decompositions exist.
