Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492476, here are decompositions:

5 + 31492471 = 31492476
23 + 31492453 = 31492476
47 + 31492429 = 31492476
53 + 31492423 = 31492476
73 + 31492403 = 31492476
83 + 31492393 = 31492476
107 + 31492369 = 31492476
139 + 31492337 = 31492476

Showing the first eight; more decompositions exist.
