Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554692, here are decompositions:

61 + 31554631 = 31554692
73 + 31554619 = 31554692
79 + 31554613 = 31554692
109 + 31554583 = 31554692
151 + 31554541 = 31554692
181 + 31554511 = 31554692
199 + 31554493 = 31554692
229 + 31554463 = 31554692

Showing the first eight; more decompositions exist.
