Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522384, here are decompositions:

11 + 31522373 = 31522384
53 + 31522331 = 31522384
71 + 31522313 = 31522384
107 + 31522277 = 31522384
137 + 31522247 = 31522384
281 + 31522103 = 31522384
293 + 31522091 = 31522384
431 + 31521953 = 31522384

Showing the first eight; more decompositions exist.
