Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522348, here are decompositions:

17 + 31522331 = 31522348
71 + 31522277 = 31522348
101 + 31522247 = 31522348
107 + 31522241 = 31522348
167 + 31522181 = 31522348
257 + 31522091 = 31522348
461 + 31521887 = 31522348
677 + 31521671 = 31522348

Showing the first eight; more decompositions exist.
