Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475244, here are decompositions:

13 + 31475231 = 31475244
103 + 31475141 = 31475244
113 + 31475131 = 31475244
137 + 31475107 = 31475244
173 + 31475071 = 31475244
191 + 31475053 = 31475244
263 + 31474981 = 31475244
313 + 31474931 = 31475244

Showing the first eight; more decompositions exist.
