Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538382, here are decompositions:

11 + 31538371 = 31538382
53 + 31538329 = 31538382
131 + 31538251 = 31538382
179 + 31538203 = 31538382
229 + 31538153 = 31538382
241 + 31538141 = 31538382
251 + 31538131 = 31538382
269 + 31538113 = 31538382

Showing the first eight; more decompositions exist.
