Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476406, here are decompositions:

23 + 31476383 = 31476406
53 + 31476353 = 31476406
89 + 31476317 = 31476406
167 + 31476239 = 31476406
257 + 31476149 = 31476406
263 + 31476143 = 31476406
293 + 31476113 = 31476406
347 + 31476059 = 31476406

Showing the first eight; more decompositions exist.
