Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554362, here are decompositions:

79 + 31554283 = 31554362
163 + 31554199 = 31554362
181 + 31554181 = 31554362
199 + 31554163 = 31554362
241 + 31554121 = 31554362
349 + 31554013 = 31554362
379 + 31553983 = 31554362
601 + 31553761 = 31554362

Showing the first eight; more decompositions exist.
