Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514030, here are decompositions:

7 + 31514023 = 31514030
43 + 31513987 = 31514030
73 + 31513957 = 31514030
103 + 31513927 = 31514030
139 + 31513891 = 31514030
151 + 31513879 = 31514030
157 + 31513873 = 31514030
181 + 31513849 = 31514030

Showing the first eight; more decompositions exist.
