Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608488, here are decompositions:

7 + 31608481 = 31608488
61 + 31608427 = 31608488
139 + 31608349 = 31608488
151 + 31608337 = 31608488
271 + 31608217 = 31608488
397 + 31608091 = 31608488
421 + 31608067 = 31608488
619 + 31607869 = 31608488

Showing the first eight; more decompositions exist.
