Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623358, here are decompositions:

101 + 31623257 = 31623358
149 + 31623209 = 31623358
191 + 31623167 = 31623358
311 + 31623047 = 31623358
317 + 31623041 = 31623358
419 + 31622939 = 31623358
521 + 31622837 = 31623358
617 + 31622741 = 31623358

Showing the first eight; more decompositions exist.
