Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537906, here are decompositions:

3 + 31537903 = 31537906
17 + 31537889 = 31537906
47 + 31537859 = 31537906
83 + 31537823 = 31537906
347 + 31537559 = 31537906
359 + 31537547 = 31537906
593 + 31537313 = 31537906
599 + 31537307 = 31537906

Showing the first eight; more decompositions exist.
