Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483738, here are decompositions:

5 + 31483733 = 31483738
47 + 31483691 = 31483738
89 + 31483649 = 31483738
191 + 31483547 = 31483738
269 + 31483469 = 31483738
281 + 31483457 = 31483738
347 + 31483391 = 31483738
431 + 31483307 = 31483738

Showing the first eight; more decompositions exist.
