Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472312, here are decompositions:

19 + 31472293 = 31472312
73 + 31472239 = 31472312
103 + 31472209 = 31472312
163 + 31472149 = 31472312
181 + 31472131 = 31472312
271 + 31472041 = 31472312
283 + 31472029 = 31472312
373 + 31471939 = 31472312

Showing the first eight; more decompositions exist.
