Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509294, here are decompositions:

23 + 31509271 = 31509294
43 + 31509251 = 31509294
73 + 31509221 = 31509294
137 + 31509157 = 31509294
233 + 31509061 = 31509294
241 + 31509053 = 31509294
263 + 31509031 = 31509294
277 + 31509017 = 31509294

Showing the first eight; more decompositions exist.
