Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609554, here are decompositions:

5 + 31609549 = 31609554
7 + 31609547 = 31609554
13 + 31609541 = 31609554
23 + 31609531 = 31609554
61 + 31609493 = 31609554
73 + 31609481 = 31609554
101 + 31609453 = 31609554
103 + 31609451 = 31609554

Showing the first eight; more decompositions exist.
