Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522360, here are decompositions:

3 + 31522357 = 31522360
29 + 31522331 = 31522360
47 + 31522313 = 31522360
83 + 31522277 = 31522360
113 + 31522247 = 31522360
131 + 31522229 = 31522360
179 + 31522181 = 31522360
257 + 31522103 = 31522360

Showing the first eight; more decompositions exist.
