Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538294, here are decompositions:

43 + 31538251 = 31538294
157 + 31538137 = 31538294
163 + 31538131 = 31538294
181 + 31538113 = 31538294
223 + 31538071 = 31538294
241 + 31538053 = 31538294
313 + 31537981 = 31538294
373 + 31537921 = 31538294

Showing the first eight; more decompositions exist.
