Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541948, here are decompositions:

79 + 31541869 = 31541948
211 + 31541737 = 31541948
241 + 31541707 = 31541948
271 + 31541677 = 31541948
337 + 31541611 = 31541948
367 + 31541581 = 31541948
379 + 31541569 = 31541948
421 + 31541527 = 31541948

Showing the first eight; more decompositions exist.
