Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622158, here are decompositions:

5 + 31622153 = 31622158
11 + 31622147 = 31622158
17 + 31622141 = 31622158
179 + 31621979 = 31622158
257 + 31621901 = 31622158
311 + 31621847 = 31622158
419 + 31621739 = 31622158
479 + 31621679 = 31622158

Showing the first eight; more decompositions exist.
