Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554556, here are decompositions:

17 + 31554539 = 31554556
29 + 31554527 = 31554556
83 + 31554473 = 31554556
107 + 31554449 = 31554556
269 + 31554287 = 31554556
479 + 31554077 = 31554556
563 + 31553993 = 31554556
569 + 31553987 = 31554556

Showing the first eight; more decompositions exist.
