Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609706, here are decompositions:

3 + 31609703 = 31609706
13 + 31609693 = 31609706
97 + 31609609 = 31609706
157 + 31609549 = 31609706
313 + 31609393 = 31609706
367 + 31609339 = 31609706
439 + 31609267 = 31609706
613 + 31609093 = 31609706

Showing the first eight; more decompositions exist.
