Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595662, here are decompositions:

5 + 31595657 = 31595662
89 + 31595573 = 31595662
179 + 31595483 = 31595662
269 + 31595393 = 31595662
383 + 31595279 = 31595662
389 + 31595273 = 31595662
419 + 31595243 = 31595662
443 + 31595219 = 31595662

Showing the first eight; more decompositions exist.
