Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475236, here are decompositions:

5 + 31475231 = 31475236
47 + 31475189 = 31475236
137 + 31475099 = 31475236
167 + 31475069 = 31475236
227 + 31475009 = 31475236
239 + 31474997 = 31475236
503 + 31474733 = 31475236
563 + 31474673 = 31475236

Showing the first eight; more decompositions exist.
