Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483834, here are decompositions:

101 + 31483733 = 31483834
251 + 31483583 = 31483834
257 + 31483577 = 31483834
281 + 31483553 = 31483834
401 + 31483433 = 31483834
443 + 31483391 = 31483834
521 + 31483313 = 31483834
617 + 31483217 = 31483834

Showing the first eight; more decompositions exist.
