Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574996, here are decompositions:

7 + 31574989 = 31574996
109 + 31574887 = 31574996
223 + 31574773 = 31574996
307 + 31574689 = 31574996
433 + 31574563 = 31574996
499 + 31574497 = 31574996
547 + 31574449 = 31574996
577 + 31574419 = 31574996

Showing the first eight; more decompositions exist.
