Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496394, here are decompositions:

5 + 31496389 = 31496394
23 + 31496371 = 31496394
73 + 31496321 = 31496394
101 + 31496293 = 31496394
131 + 31496263 = 31496394
173 + 31496221 = 31496394
233 + 31496161 = 31496394
271 + 31496123 = 31496394

Showing the first eight; more decompositions exist.
