Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580176, here are decompositions:

83 + 31580093 = 31580176
113 + 31580063 = 31580176
167 + 31580009 = 31580176
263 + 31579913 = 31580176
317 + 31579859 = 31580176
557 + 31579619 = 31580176
983 + 31579193 = 31580176
1049 + 31579127 = 31580176

Showing the first eight; more decompositions exist.
