Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547442, here are decompositions:

29 + 31547413 = 31547442
103 + 31547339 = 31547442
139 + 31547303 = 31547442
181 + 31547261 = 31547442
211 + 31547231 = 31547442
233 + 31547209 = 31547442
239 + 31547203 = 31547442
281 + 31547161 = 31547442

Showing the first eight; more decompositions exist.
