Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483642, here are decompositions:

59 + 31483583 = 31483642
89 + 31483553 = 31483642
149 + 31483493 = 31483642
173 + 31483469 = 31483642
251 + 31483391 = 31483642
479 + 31483163 = 31483642
809 + 31482833 = 31483642
821 + 31482821 = 31483642

Showing the first eight; more decompositions exist.
