Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559404, here are decompositions:

3 + 31559401 = 31559404
53 + 31559351 = 31559404
83 + 31559321 = 31559404
197 + 31559207 = 31559404
311 + 31559093 = 31559404
353 + 31559051 = 31559404
431 + 31558973 = 31559404
521 + 31558883 = 31559404

Showing the first eight; more decompositions exist.
