Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493606, here are decompositions:

7 + 31493599 = 31493606
13 + 31493593 = 31493606
37 + 31493569 = 31493606
73 + 31493533 = 31493606
139 + 31493467 = 31493606
163 + 31493443 = 31493606
229 + 31493377 = 31493606
283 + 31493323 = 31493606

Showing the first eight; more decompositions exist.
