Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493496, here are decompositions:

19 + 31493477 = 31493496
29 + 31493467 = 31493496
53 + 31493443 = 31493496
149 + 31493347 = 31493496
157 + 31493339 = 31493496
173 + 31493323 = 31493496
439 + 31493057 = 31493496
443 + 31493053 = 31493496

Showing the first eight; more decompositions exist.
