Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472342, here are decompositions:

3 + 31472339 = 31472342
103 + 31472239 = 31472342
151 + 31472191 = 31472342
163 + 31472179 = 31472342
193 + 31472149 = 31472342
199 + 31472143 = 31472342
211 + 31472131 = 31472342
313 + 31472029 = 31472342

Showing the first eight; more decompositions exist.
