Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475932, here are decompositions:

3 + 31475929 = 31475932
23 + 31475909 = 31475932
83 + 31475849 = 31475932
251 + 31475681 = 31475932
263 + 31475669 = 31475932
353 + 31475579 = 31475932
443 + 31475489 = 31475932
461 + 31475471 = 31475932

Showing the first eight; more decompositions exist.
