Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475562, here are decompositions:

71 + 31475491 = 31475562
73 + 31475489 = 31475562
103 + 31475459 = 31475562
109 + 31475453 = 31475562
191 + 31475371 = 31475562
241 + 31475321 = 31475562
311 + 31475251 = 31475562
331 + 31475231 = 31475562

Showing the first eight; more decompositions exist.
