Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575596, here are decompositions:

43 + 31575553 = 31575596
97 + 31575499 = 31575596
109 + 31575487 = 31575596
127 + 31575469 = 31575596
163 + 31575433 = 31575596
379 + 31575217 = 31575596
433 + 31575163 = 31575596
457 + 31575139 = 31575596

Showing the first eight; more decompositions exist.
