Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623492, here are decompositions:

11 + 31623481 = 31623492
13 + 31623479 = 31623492
31 + 31623461 = 31623492
53 + 31623439 = 31623492
71 + 31623421 = 31623492
149 + 31623343 = 31623492
269 + 31623223 = 31623492
281 + 31623211 = 31623492

Showing the first eight; more decompositions exist.
