Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493564, here are decompositions:

7 + 31493557 = 31493564
31 + 31493533 = 31493564
43 + 31493521 = 31493564
97 + 31493467 = 31493564
211 + 31493353 = 31493564
241 + 31493323 = 31493564
313 + 31493251 = 31493564
373 + 31493191 = 31493564

Showing the first eight; more decompositions exist.
