Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576324, here are decompositions:

41 + 31576283 = 31576324
71 + 31576253 = 31576324
83 + 31576241 = 31576324
113 + 31576211 = 31576324
137 + 31576187 = 31576324
233 + 31576091 = 31576324
257 + 31576067 = 31576324
293 + 31576031 = 31576324

Showing the first eight; more decompositions exist.
