Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931372, here are decompositions:

53 + 931319 = 931372
59 + 931313 = 931372
83 + 931289 = 931372
131 + 931241 = 931372
173 + 931199 = 931372
179 + 931193 = 931372
191 + 931181 = 931372
359 + 931013 = 931372

Showing the first eight; more decompositions exist.
