Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492406, here are decompositions:

3 + 31492403 = 31492406
7 + 31492399 = 31492406
13 + 31492393 = 31492406
37 + 31492369 = 31492406
163 + 31492243 = 31492406
193 + 31492213 = 31492406
313 + 31492093 = 31492406
373 + 31492033 = 31492406

Showing the first eight; more decompositions exist.
