Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575104, here are decompositions:

13 + 31575091 = 31575104
31 + 31575073 = 31575104
193 + 31574911 = 31575104
241 + 31574863 = 31575104
283 + 31574821 = 31575104
331 + 31574773 = 31575104
433 + 31574671 = 31575104
541 + 31574563 = 31575104

Showing the first eight; more decompositions exist.
