Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575536, here are decompositions:

37 + 31575499 = 31575536
67 + 31575469 = 31575536
103 + 31575433 = 31575536
199 + 31575337 = 31575536
373 + 31575163 = 31575536
397 + 31575139 = 31575536
463 + 31575073 = 31575536
547 + 31574989 = 31575536

Showing the first eight; more decompositions exist.
