Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89172, here are decompositions:

19 + 89153 = 89172
53 + 89119 = 89172
59 + 89113 = 89172
71 + 89101 = 89172
89 + 89083 = 89172
101 + 89071 = 89172
103 + 89069 = 89172
131 + 89041 = 89172

Showing the first eight; more decompositions exist.
