Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579196, here are decompositions:

3 + 31579193 = 31579196
67 + 31579129 = 31579196
97 + 31579099 = 31579196
109 + 31579087 = 31579196
157 + 31579039 = 31579196
193 + 31579003 = 31579196
223 + 31578973 = 31579196
277 + 31578919 = 31579196

Showing the first eight; more decompositions exist.
