Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971228, here are decompositions:

31 + 971197 = 971228
79 + 971149 = 971228
151 + 971077 = 971228
199 + 971029 = 971228
229 + 970999 = 971228
241 + 970987 = 971228
367 + 970861 = 971228
439 + 970789 = 971228

Showing the first eight; more decompositions exist.
