Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483554, here are decompositions:

5 + 31483549 = 31483554
7 + 31483547 = 31483554
61 + 31483493 = 31483554
83 + 31483471 = 31483554
97 + 31483457 = 31483554
101 + 31483453 = 31483554
107 + 31483447 = 31483554
163 + 31483391 = 31483554

Showing the first eight; more decompositions exist.
