Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492410, here are decompositions:

7 + 31492403 = 31492410
11 + 31492399 = 31492410
17 + 31492393 = 31492410
41 + 31492369 = 31492410
73 + 31492337 = 31492410
149 + 31492261 = 31492410
151 + 31492259 = 31492410
167 + 31492243 = 31492410

Showing the first eight; more decompositions exist.
