Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576348, here are decompositions:

59 + 31576289 = 31576348
107 + 31576241 = 31576348
137 + 31576211 = 31576348
149 + 31576199 = 31576348
179 + 31576169 = 31576348
227 + 31576121 = 31576348
257 + 31576091 = 31576348
281 + 31576067 = 31576348

Showing the first eight; more decompositions exist.
