Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609476, here are decompositions:

7 + 31609469 = 31609476
13 + 31609463 = 31609476
23 + 31609453 = 31609476
83 + 31609393 = 31609476
137 + 31609339 = 31609476
263 + 31609213 = 31609476
359 + 31609117 = 31609476
383 + 31609093 = 31609476

Showing the first eight; more decompositions exist.
