Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622362, here are decompositions:

89 + 31622273 = 31622362
173 + 31622189 = 31622362
179 + 31622183 = 31622362
281 + 31622081 = 31622362
383 + 31621979 = 31622362
461 + 31621901 = 31622362
659 + 31621703 = 31622362
683 + 31621679 = 31622362

Showing the first eight; more decompositions exist.
