Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623592, here are decompositions:

3 + 31623589 = 31623592
71 + 31623521 = 31623592
83 + 31623509 = 31623592
101 + 31623491 = 31623592
113 + 31623479 = 31623592
131 + 31623461 = 31623592
149 + 31623443 = 31623592
383 + 31623209 = 31623592

Showing the first eight; more decompositions exist.
