Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971380, here are decompositions:

23 + 971357 = 971380
41 + 971339 = 971380
71 + 971309 = 971380
89 + 971291 = 971380
101 + 971279 = 971380
107 + 971273 = 971380
173 + 971207 = 971380
227 + 971153 = 971380

Showing the first eight; more decompositions exist.
