Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670172, here are decompositions:

83 + 8670089 = 8670172
101 + 8670071 = 8670172
131 + 8670041 = 8670172
179 + 8669993 = 8670172
191 + 8669981 = 8670172
233 + 8669939 = 8670172
293 + 8669879 = 8670172
311 + 8669861 = 8670172

Showing the first eight; more decompositions exist.
