Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623356, here are decompositions:

13 + 31623343 = 31623356
19 + 31623337 = 31623356
157 + 31623199 = 31623356
397 + 31622959 = 31623356
409 + 31622947 = 31623356
433 + 31622923 = 31623356
463 + 31622893 = 31623356
547 + 31622809 = 31623356

Showing the first eight; more decompositions exist.
