Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531934, here are decompositions:

3 + 31531931 = 31531934
13 + 31531921 = 31531934
307 + 31531627 = 31531934
463 + 31531471 = 31531934
631 + 31531303 = 31531934
661 + 31531273 = 31531934
673 + 31531261 = 31531934
877 + 31531057 = 31531934

Showing the first eight; more decompositions exist.
