Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931420, here are decompositions:

3 + 931417 = 931420
101 + 931319 = 931420
107 + 931313 = 931420
131 + 931289 = 931420
179 + 931241 = 931420
227 + 931193 = 931420
239 + 931181 = 931420
251 + 931169 = 931420

Showing the first eight; more decompositions exist.
