Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546758, here are decompositions:

17 + 31546741 = 31546758
37 + 31546721 = 31546758
41 + 31546717 = 31546758
97 + 31546661 = 31546758
101 + 31546657 = 31546758
137 + 31546621 = 31546758
157 + 31546601 = 31546758
167 + 31546591 = 31546758

Showing the first eight; more decompositions exist.
