Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623892, here are decompositions:

5 + 31623887 = 31623892
71 + 31623821 = 31623892
191 + 31623701 = 31623892
269 + 31623623 = 31623892
383 + 31623509 = 31623892
401 + 31623491 = 31623892
431 + 31623461 = 31623892
449 + 31623443 = 31623892

Showing the first eight; more decompositions exist.
