Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475546, here are decompositions:

103 + 31475443 = 31475546
139 + 31475407 = 31475546
229 + 31475317 = 31475546
337 + 31475209 = 31475546
439 + 31475107 = 31475546
457 + 31475089 = 31475546
463 + 31475083 = 31475546
547 + 31474999 = 31475546

Showing the first eight; more decompositions exist.
