Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609676, here are decompositions:

67 + 31609609 = 31609676
127 + 31609549 = 31609676
157 + 31609519 = 31609676
223 + 31609453 = 31609676
283 + 31609393 = 31609676
337 + 31609339 = 31609676
409 + 31609267 = 31609676
463 + 31609213 = 31609676

Showing the first eight; more decompositions exist.
