Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514898, here are decompositions:

5 + 31514893 = 31514898
29 + 31514869 = 31514898
59 + 31514839 = 31514898
61 + 31514837 = 31514898
109 + 31514789 = 31514898
127 + 31514771 = 31514898
157 + 31514741 = 31514898
167 + 31514731 = 31514898

Showing the first eight; more decompositions exist.
