Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472394, here are decompositions:

43 + 31472351 = 31472394
101 + 31472293 = 31472394
103 + 31472291 = 31472394
193 + 31472201 = 31472394
211 + 31472183 = 31472394
227 + 31472167 = 31472394
241 + 31472153 = 31472394
251 + 31472143 = 31472394

Showing the first eight; more decompositions exist.
