Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575764, here are decompositions:

37 + 31575727 = 31575764
67 + 31575697 = 31575764
97 + 31575667 = 31575764
127 + 31575637 = 31575764
193 + 31575571 = 31575764
211 + 31575553 = 31575764
277 + 31575487 = 31575764
331 + 31575433 = 31575764

Showing the first eight; more decompositions exist.
