Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980172, here are decompositions:

13 + 980159 = 980172
23 + 980149 = 980172
41 + 980131 = 980172
101 + 980071 = 980172
103 + 980069 = 980172
223 + 979949 = 980172
251 + 979921 = 980172
283 + 979889 = 980172

Showing the first eight; more decompositions exist.
