Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492606, here are decompositions:

3 + 31492603 = 31492606
29 + 31492577 = 31492606
53 + 31492553 = 31492606
113 + 31492493 = 31492606
269 + 31492337 = 31492606
347 + 31492259 = 31492606
443 + 31492163 = 31492606
449 + 31492157 = 31492606

Showing the first eight; more decompositions exist.
