Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493834, here are decompositions:

13 + 31493821 = 31493834
157 + 31493677 = 31493834
181 + 31493653 = 31493834
193 + 31493641 = 31493834
223 + 31493611 = 31493834
241 + 31493593 = 31493834
277 + 31493557 = 31493834
313 + 31493521 = 31493834

Showing the first eight; more decompositions exist.
