Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576318, here are decompositions:

29 + 31576289 = 31576318
107 + 31576211 = 31576318
131 + 31576187 = 31576318
149 + 31576169 = 31576318
197 + 31576121 = 31576318
227 + 31576091 = 31576318
251 + 31576067 = 31576318
269 + 31576049 = 31576318

Showing the first eight; more decompositions exist.
