Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514084, here are decompositions:

3 + 31514081 = 31514084
61 + 31514023 = 31514084
97 + 31513987 = 31514084
127 + 31513957 = 31514084
157 + 31513927 = 31514084
193 + 31513891 = 31514084
211 + 31513873 = 31514084
241 + 31513843 = 31514084

Showing the first eight; more decompositions exist.
