Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579032, here are decompositions:

29 + 31579003 = 31579032
59 + 31578973 = 31579032
83 + 31578949 = 31579032
103 + 31578929 = 31579032
109 + 31578923 = 31579032
113 + 31578919 = 31579032
151 + 31578881 = 31579032
211 + 31578821 = 31579032

Showing the first eight; more decompositions exist.
