Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513592, here are decompositions:

13 + 31513579 = 31513592
31 + 31513561 = 31513592
181 + 31513411 = 31513592
283 + 31513309 = 31513592
373 + 31513219 = 31513592
379 + 31513213 = 31513592
601 + 31512991 = 31513592
751 + 31512841 = 31513592

Showing the first eight; more decompositions exist.
