Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514962, here are decompositions:

29 + 31514933 = 31514962
113 + 31514849 = 31514962
173 + 31514789 = 31514962
179 + 31514783 = 31514962
191 + 31514771 = 31514962
383 + 31514579 = 31514962
389 + 31514573 = 31514962
449 + 31514513 = 31514962

Showing the first eight; more decompositions exist.
