Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541950, here are decompositions:

17 + 31541933 = 31541950
47 + 31541903 = 31541950
59 + 31541891 = 31541950
257 + 31541693 = 31541950
317 + 31541633 = 31541950
353 + 31541597 = 31541950
359 + 31541591 = 31541950
443 + 31541507 = 31541950

Showing the first eight; more decompositions exist.
