Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603954, here are decompositions:

23 + 31603931 = 31603954
197 + 31603757 = 31603954
233 + 31603721 = 31603954
311 + 31603643 = 31603954
401 + 31603553 = 31603954
443 + 31603511 = 31603954
467 + 31603487 = 31603954
587 + 31603367 = 31603954

Showing the first eight; more decompositions exist.
