Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931438, here are decompositions:

17 + 931421 = 931438
149 + 931289 = 931438
197 + 931241 = 931438
239 + 931199 = 931438
257 + 931181 = 931438
269 + 931169 = 931438
311 + 931127 = 931438
449 + 930989 = 931438

Showing the first eight; more decompositions exist.
