Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513614, here are decompositions:

7 + 31513607 = 31513614
53 + 31513561 = 31513614
191 + 31513423 = 31513614
211 + 31513403 = 31513614
241 + 31513373 = 31513614
281 + 31513333 = 31513614
283 + 31513331 = 31513614
311 + 31513303 = 31513614

Showing the first eight; more decompositions exist.
