Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496338, here are decompositions:

17 + 31496321 = 31496338
197 + 31496141 = 31496338
239 + 31496099 = 31496338
281 + 31496057 = 31496338
311 + 31496027 = 31496338
359 + 31495979 = 31496338
389 + 31495949 = 31496338
479 + 31495859 = 31496338

Showing the first eight; more decompositions exist.
