Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554126, here are decompositions:

5 + 31554121 = 31554126
53 + 31554073 = 31554126
83 + 31554043 = 31554126
113 + 31554013 = 31554126
139 + 31553987 = 31554126
223 + 31553903 = 31554126
293 + 31553833 = 31554126
349 + 31553777 = 31554126

Showing the first eight; more decompositions exist.
