Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514324, here are decompositions:

103 + 31514221 = 31514324
181 + 31514143 = 31514324
211 + 31514113 = 31514324
223 + 31514101 = 31514324
337 + 31513987 = 31514324
367 + 31513957 = 31514324
397 + 31513927 = 31514324
433 + 31513891 = 31514324

Showing the first eight; more decompositions exist.
