Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475606, here are decompositions:

7 + 31475599 = 31475606
163 + 31475443 = 31475606
199 + 31475407 = 31475606
397 + 31475209 = 31475606
499 + 31475107 = 31475606
523 + 31475083 = 31475606
577 + 31475029 = 31475606
607 + 31474999 = 31475606

Showing the first eight; more decompositions exist.
