Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541644, here are decompositions:

11 + 31541633 = 31541644
47 + 31541597 = 31541644
53 + 31541591 = 31541644
137 + 31541507 = 31541644
227 + 31541417 = 31541644
347 + 31541297 = 31541644
401 + 31541243 = 31541644
503 + 31541141 = 31541644

Showing the first eight; more decompositions exist.
