Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522294, here are decompositions:

17 + 31522277 = 31522294
47 + 31522247 = 31522294
53 + 31522241 = 31522294
113 + 31522181 = 31522294
191 + 31522103 = 31522294
233 + 31522061 = 31522294
281 + 31522013 = 31522294
317 + 31521977 = 31522294

Showing the first eight; more decompositions exist.
