Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475544, here are decompositions:

53 + 31475491 = 31475544
73 + 31475471 = 31475544
101 + 31475443 = 31475544
137 + 31475407 = 31475544
151 + 31475393 = 31475544
157 + 31475387 = 31475544
173 + 31475371 = 31475544
223 + 31475321 = 31475544

Showing the first eight; more decompositions exist.
