Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579026, here are decompositions:

23 + 31579003 = 31579026
53 + 31578973 = 31579026
79 + 31578947 = 31579026
97 + 31578929 = 31579026
103 + 31578923 = 31579026
107 + 31578919 = 31579026
139 + 31578887 = 31579026
239 + 31578787 = 31579026

Showing the first eight; more decompositions exist.
