Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579106, here are decompositions:

3 + 31579103 = 31579106
7 + 31579099 = 31579106
19 + 31579087 = 31579106
67 + 31579039 = 31579106
103 + 31579003 = 31579106
157 + 31578949 = 31579106
409 + 31578697 = 31579106
499 + 31578607 = 31579106

Showing the first eight; more decompositions exist.
