Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678100, here are decompositions:

7 + 8678093 = 8678100
17 + 8678083 = 8678100
19 + 8678081 = 8678100
31 + 8678069 = 8678100
37 + 8678063 = 8678100
43 + 8678057 = 8678100
47 + 8678053 = 8678100
61 + 8678039 = 8678100

Showing the first eight; more decompositions exist.
