Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971390, here are decompositions:

3 + 971387 = 971390
19 + 971371 = 971390
37 + 971353 = 971390
109 + 971281 = 971390
127 + 971263 = 971390
139 + 971251 = 971390
193 + 971197 = 971390
241 + 971149 = 971390

Showing the first eight; more decompositions exist.
