Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514932, here are decompositions:

83 + 31514849 = 31514932
149 + 31514783 = 31514932
191 + 31514741 = 31514932
269 + 31514663 = 31514932
353 + 31514579 = 31514932
359 + 31514573 = 31514932
419 + 31514513 = 31514932
503 + 31514429 = 31514932

Showing the first eight; more decompositions exist.
