Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576122, here are decompositions:

5 + 31576117 = 31576122
31 + 31576091 = 31576122
73 + 31576049 = 31576122
113 + 31576009 = 31576122
131 + 31575991 = 31576122
199 + 31575923 = 31576122
223 + 31575899 = 31576122
229 + 31575893 = 31576122

Showing the first eight; more decompositions exist.
