Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475804, here are decompositions:

7 + 31475797 = 31475804
127 + 31475677 = 31475804
181 + 31475623 = 31475804
193 + 31475611 = 31475804
223 + 31475581 = 31475804
313 + 31475491 = 31475804
397 + 31475407 = 31475804
433 + 31475371 = 31475804

Showing the first eight; more decompositions exist.
