Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579110, here are decompositions:

7 + 31579103 = 31579110
11 + 31579099 = 31579110
19 + 31579091 = 31579110
23 + 31579087 = 31579110
37 + 31579073 = 31579110
71 + 31579039 = 31579110
107 + 31579003 = 31579110
137 + 31578973 = 31579110

Showing the first eight; more decompositions exist.
