Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514012, here are decompositions:

139 + 31513873 = 31514012
163 + 31513849 = 31514012
181 + 31513831 = 31514012
193 + 31513819 = 31514012
433 + 31513579 = 31514012
601 + 31513411 = 31514012
709 + 31513303 = 31514012
811 + 31513201 = 31514012

Showing the first eight; more decompositions exist.
