Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609484, here are decompositions:

3 + 31609481 = 31609484
31 + 31609453 = 31609484
103 + 31609381 = 31609484
271 + 31609213 = 31609484
367 + 31609117 = 31609484
373 + 31609111 = 31609484
397 + 31609087 = 31609484
547 + 31608937 = 31609484

Showing the first eight; more decompositions exist.
