Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493654, here are decompositions:

13 + 31493641 = 31493654
43 + 31493611 = 31493654
61 + 31493593 = 31493654
97 + 31493557 = 31493654
211 + 31493443 = 31493654
277 + 31493377 = 31493654
307 + 31493347 = 31493654
331 + 31493323 = 31493654

Showing the first eight; more decompositions exist.
