Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541944, here are decompositions:

11 + 31541933 = 31541944
41 + 31541903 = 31541944
53 + 31541891 = 31541944
251 + 31541693 = 31541944
293 + 31541651 = 31541944
311 + 31541633 = 31541944
347 + 31541597 = 31541944
353 + 31541591 = 31541944

Showing the first eight; more decompositions exist.
