Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679172, here are decompositions:

101 + 8679071 = 8679172
113 + 8679059 = 8679172
233 + 8678939 = 8679172
239 + 8678933 = 8679172
269 + 8678903 = 8679172
389 + 8678783 = 8679172
419 + 8678753 = 8679172
431 + 8678741 = 8679172

Showing the first eight; more decompositions exist.
