Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536922, here are decompositions:

5 + 31536917 = 31536922
59 + 31536863 = 31536922
101 + 31536821 = 31536922
149 + 31536773 = 31536922
191 + 31536731 = 31536922
293 + 31536629 = 31536922
383 + 31536539 = 31536922
401 + 31536521 = 31536922

Showing the first eight; more decompositions exist.
