Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493624, here are decompositions:

13 + 31493611 = 31493624
31 + 31493593 = 31493624
67 + 31493557 = 31493624
103 + 31493521 = 31493624
157 + 31493467 = 31493624
181 + 31493443 = 31493624
271 + 31493353 = 31493624
277 + 31493347 = 31493624

Showing the first eight; more decompositions exist.
