Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500962, here are decompositions:

43 + 31500919 = 31500962
109 + 31500853 = 31500962
271 + 31500691 = 31500962
313 + 31500649 = 31500962
373 + 31500589 = 31500962
433 + 31500529 = 31500962
499 + 31500463 = 31500962
601 + 31500361 = 31500962

Showing the first eight; more decompositions exist.
