Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591662, here are decompositions:

13 + 31591649 = 31591662
59 + 31591603 = 31591662
61 + 31591601 = 31591662
149 + 31591513 = 31591662
163 + 31591499 = 31591662
241 + 31591421 = 31591662
281 + 31591381 = 31591662
313 + 31591349 = 31591662

Showing the first eight; more decompositions exist.
