Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522408, here are decompositions:

131 + 31522277 = 31522408
167 + 31522241 = 31522408
179 + 31522229 = 31522408
227 + 31522181 = 31522408
317 + 31522091 = 31522408
347 + 31522061 = 31522408
389 + 31522019 = 31522408
431 + 31521977 = 31522408

Showing the first eight; more decompositions exist.
