Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514144, here are decompositions:

31 + 31514113 = 31514144
43 + 31514101 = 31514144
157 + 31513987 = 31514144
271 + 31513873 = 31514144
313 + 31513831 = 31514144
523 + 31513621 = 31514144
733 + 31513411 = 31514144
811 + 31513333 = 31514144

Showing the first eight; more decompositions exist.
