Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554086, here are decompositions:

13 + 31554073 = 31554086
43 + 31554043 = 31554086
73 + 31554013 = 31554086
103 + 31553983 = 31554086
283 + 31553803 = 31554086
367 + 31553719 = 31554086
379 + 31553707 = 31554086
727 + 31553359 = 31554086

Showing the first eight; more decompositions exist.
