Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623434, here are decompositions:

13 + 31623421 = 31623434
61 + 31623373 = 31623434
97 + 31623337 = 31623434
211 + 31623223 = 31623434
223 + 31623211 = 31623434
313 + 31623121 = 31623434
373 + 31623061 = 31623434
487 + 31622947 = 31623434

Showing the first eight; more decompositions exist.
