Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464634, here are decompositions:

17 + 31464617 = 31464634
53 + 31464581 = 31464634
191 + 31464443 = 31464634
233 + 31464401 = 31464634
293 + 31464341 = 31464634
353 + 31464281 = 31464634
401 + 31464233 = 31464634
491 + 31464143 = 31464634

Showing the first eight; more decompositions exist.
