Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493702, here are decompositions:

13 + 31493689 = 31493702
61 + 31493641 = 31493702
103 + 31493599 = 31493702
109 + 31493593 = 31493702
181 + 31493521 = 31493702
283 + 31493419 = 31493702
349 + 31493353 = 31493702
379 + 31493323 = 31493702

Showing the first eight; more decompositions exist.
