Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514760, here are decompositions:

19 + 31514741 = 31514760
29 + 31514731 = 31514760
71 + 31514689 = 31514760
73 + 31514687 = 31514760
89 + 31514671 = 31514760
97 + 31514663 = 31514760
107 + 31514653 = 31514760
131 + 31514629 = 31514760

Showing the first eight; more decompositions exist.
