Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554194, here are decompositions:

13 + 31554181 = 31554194
31 + 31554163 = 31554194
73 + 31554121 = 31554194
151 + 31554043 = 31554194
181 + 31554013 = 31554194
211 + 31553983 = 31554194
433 + 31553761 = 31554194
487 + 31553707 = 31554194

Showing the first eight; more decompositions exist.
