Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514806, here are decompositions:

17 + 31514789 = 31514806
23 + 31514783 = 31514806
179 + 31514627 = 31514806
227 + 31514579 = 31514806
233 + 31514573 = 31514806
269 + 31514537 = 31514806
293 + 31514513 = 31514806
383 + 31514423 = 31514806

Showing the first eight; more decompositions exist.
