Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609626, here are decompositions:

17 + 31609609 = 31609626
43 + 31609583 = 31609626
79 + 31609547 = 31609626
107 + 31609519 = 31609626
127 + 31609499 = 31609626
157 + 31609469 = 31609626
163 + 31609463 = 31609626
173 + 31609453 = 31609626

Showing the first eight; more decompositions exist.
