Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482492, here are decompositions:

53 + 31482439 = 31482492
103 + 31482389 = 31482492
149 + 31482343 = 31482492
199 + 31482293 = 31482492
211 + 31482281 = 31482492
263 + 31482229 = 31482492
313 + 31482179 = 31482492
373 + 31482119 = 31482492

Showing the first eight; more decompositions exist.
