Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541946, here are decompositions:

13 + 31541933 = 31541946
43 + 31541903 = 31541946
47 + 31541899 = 31541946
53 + 31541893 = 31541946
89 + 31541857 = 31541946
239 + 31541707 = 31541946
269 + 31541677 = 31541946
313 + 31541633 = 31541946

Showing the first eight; more decompositions exist.
