Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514584, here are decompositions:

5 + 31514579 = 31514584
11 + 31514573 = 31514584
47 + 31514537 = 31514584
71 + 31514513 = 31514584
107 + 31514477 = 31514584
293 + 31514291 = 31514584
317 + 31514267 = 31514584
503 + 31514081 = 31514584

Showing the first eight; more decompositions exist.
