Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483558, here are decompositions:

5 + 31483553 = 31483558
11 + 31483547 = 31483558
89 + 31483469 = 31483558
101 + 31483457 = 31483558
167 + 31483391 = 31483558
251 + 31483307 = 31483558
389 + 31483169 = 31483558
461 + 31483097 = 31483558

Showing the first eight; more decompositions exist.
