Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472088, here are decompositions:

19 + 31472069 = 31472088
47 + 31472041 = 31472088
59 + 31472029 = 31472088
97 + 31471991 = 31472088
149 + 31471939 = 31472088
181 + 31471907 = 31472088
239 + 31471849 = 31472088
257 + 31471831 = 31472088

Showing the first eight; more decompositions exist.
