Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931390, here are decompositions:

3 + 931387 = 931390
71 + 931319 = 931390
101 + 931289 = 931390
149 + 931241 = 931390
191 + 931199 = 931390
197 + 931193 = 931390
227 + 931163 = 931390
263 + 931127 = 931390

Showing the first eight; more decompositions exist.
