Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575932, here are decompositions:

103 + 31575829 = 31575932
109 + 31575823 = 31575932
139 + 31575793 = 31575932
163 + 31575769 = 31575932
379 + 31575553 = 31575932
433 + 31575499 = 31575932
463 + 31575469 = 31575932
499 + 31575433 = 31575932

Showing the first eight; more decompositions exist.
