Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567380, here are decompositions:

11 + 31567369 = 31567380
67 + 31567313 = 31567380
83 + 31567297 = 31567380
101 + 31567279 = 31567380
109 + 31567271 = 31567380
113 + 31567267 = 31567380
139 + 31567241 = 31567380
149 + 31567231 = 31567380

Showing the first eight; more decompositions exist.
