Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514246, here are decompositions:

7 + 31514239 = 31514246
97 + 31514149 = 31514246
103 + 31514143 = 31514246
223 + 31514023 = 31514246
367 + 31513879 = 31514246
373 + 31513873 = 31514246
397 + 31513849 = 31514246
823 + 31513423 = 31514246

Showing the first eight; more decompositions exist.
