Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514766, here are decompositions:

79 + 31514687 = 31514766
103 + 31514663 = 31514766
113 + 31514653 = 31514766
137 + 31514629 = 31514766
139 + 31514627 = 31514766
167 + 31514599 = 31514766
193 + 31514573 = 31514766
229 + 31514537 = 31514766

Showing the first eight; more decompositions exist.
