Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554102, here are decompositions:

29 + 31554073 = 31554102
59 + 31554043 = 31554102
89 + 31554013 = 31554102
109 + 31553993 = 31554102
199 + 31553903 = 31554102
269 + 31553833 = 31554102
373 + 31553729 = 31554102
383 + 31553719 = 31554102

Showing the first eight; more decompositions exist.
