Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493708, here are decompositions:

19 + 31493689 = 31493708
31 + 31493677 = 31493708
67 + 31493641 = 31493708
97 + 31493611 = 31493708
109 + 31493599 = 31493708
139 + 31493569 = 31493708
151 + 31493557 = 31493708
241 + 31493467 = 31493708

Showing the first eight; more decompositions exist.
