Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483438, here are decompositions:

5 + 31483433 = 31483438
47 + 31483391 = 31483438
131 + 31483307 = 31483438
269 + 31483169 = 31483438
461 + 31482977 = 31483438
491 + 31482947 = 31483438
599 + 31482839 = 31483438
617 + 31482821 = 31483438

Showing the first eight; more decompositions exist.
