Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493604, here are decompositions:

5 + 31493599 = 31493604
11 + 31493593 = 31493604
31 + 31493573 = 31493604
47 + 31493557 = 31493604
71 + 31493533 = 31493604
83 + 31493521 = 31493604
127 + 31493477 = 31493604
137 + 31493467 = 31493604

Showing the first eight; more decompositions exist.
