Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522948, here are decompositions:

11 + 31522937 = 31522948
47 + 31522901 = 31522948
59 + 31522889 = 31522948
101 + 31522847 = 31522948
419 + 31522529 = 31522948
617 + 31522331 = 31522948
701 + 31522247 = 31522948
719 + 31522229 = 31522948

Showing the first eight; more decompositions exist.
