Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492396, here are decompositions:

3 + 31492393 = 31492396
59 + 31492337 = 31492396
137 + 31492259 = 31492396
233 + 31492163 = 31492396
239 + 31492157 = 31492396
317 + 31492079 = 31492396
479 + 31491917 = 31492396
503 + 31491893 = 31492396

Showing the first eight; more decompositions exist.
