Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579116, here are decompositions:

7 + 31579109 = 31579116
13 + 31579103 = 31579116
17 + 31579099 = 31579116
29 + 31579087 = 31579116
43 + 31579073 = 31579116
113 + 31579003 = 31579116
167 + 31578949 = 31579116
193 + 31578923 = 31579116

Showing the first eight; more decompositions exist.
