Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514782, here are decompositions:

11 + 31514771 = 31514782
41 + 31514741 = 31514782
269 + 31514513 = 31514782
353 + 31514429 = 31514782
359 + 31514423 = 31514782
491 + 31514291 = 31514782
521 + 31514261 = 31514782
701 + 31514081 = 31514782

Showing the first eight; more decompositions exist.
