Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472332, here are decompositions:

41 + 31472291 = 31472332
71 + 31472261 = 31472332
131 + 31472201 = 31472332
149 + 31472183 = 31472332
173 + 31472159 = 31472332
179 + 31472153 = 31472332
263 + 31472069 = 31472332
431 + 31471901 = 31472332

Showing the first eight; more decompositions exist.
