Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541196, here are decompositions:

17 + 31541179 = 31541196
23 + 31541173 = 31541196
67 + 31541129 = 31541196
79 + 31541117 = 31541196
83 + 31541113 = 31541196
149 + 31541047 = 31541196
157 + 31541039 = 31541196
179 + 31541017 = 31541196

Showing the first eight; more decompositions exist.
