Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623436, here are decompositions:

59 + 31623377 = 31623436
179 + 31623257 = 31623436
227 + 31623209 = 31623436
263 + 31623173 = 31623436
269 + 31623167 = 31623436
389 + 31623047 = 31623436
503 + 31622933 = 31623436
599 + 31622837 = 31623436

Showing the first eight; more decompositions exist.
