Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554164, here are decompositions:

3 + 31554161 = 31554164
43 + 31554121 = 31554164
151 + 31554013 = 31554164
181 + 31553983 = 31554164
331 + 31553833 = 31554164
457 + 31553707 = 31554164
547 + 31553617 = 31554164
661 + 31553503 = 31554164

Showing the first eight; more decompositions exist.
