Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554050, here are decompositions:

7 + 31554043 = 31554050
37 + 31554013 = 31554050
67 + 31553983 = 31554050
331 + 31553719 = 31554050
379 + 31553671 = 31554050
433 + 31553617 = 31554050
523 + 31553527 = 31554050
547 + 31553503 = 31554050

Showing the first eight; more decompositions exist.
