Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475598, here are decompositions:

17 + 31475581 = 31475598
19 + 31475579 = 31475598
107 + 31475491 = 31475598
109 + 31475489 = 31475598
127 + 31475471 = 31475598
139 + 31475459 = 31475598
191 + 31475407 = 31475598
197 + 31475401 = 31475598

Showing the first eight; more decompositions exist.
