Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622848, here are decompositions:

11 + 31622837 = 31622848
71 + 31622777 = 31622848
107 + 31622741 = 31622848
149 + 31622699 = 31622848
269 + 31622579 = 31622848
311 + 31622537 = 31622848
419 + 31622429 = 31622848
479 + 31622369 = 31622848

Showing the first eight; more decompositions exist.
