Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931450, here are decompositions:

29 + 931421 = 931450
131 + 931319 = 931450
137 + 931313 = 931450
251 + 931199 = 931450
257 + 931193 = 931450
269 + 931181 = 931450
281 + 931169 = 931450
353 + 931097 = 931450

Showing the first eight; more decompositions exist.
