Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554182, here are decompositions:

3 + 31554179 = 31554182
19 + 31554163 = 31554182
61 + 31554121 = 31554182
109 + 31554073 = 31554182
139 + 31554043 = 31554182
199 + 31553983 = 31554182
349 + 31553833 = 31554182
379 + 31553803 = 31554182

Showing the first eight; more decompositions exist.
