Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579024, here are decompositions:

101 + 31578923 = 31579024
137 + 31578887 = 31579024
233 + 31578791 = 31579024
293 + 31578731 = 31579024
401 + 31578623 = 31579024
443 + 31578581 = 31579024
467 + 31578557 = 31579024
593 + 31578431 = 31579024

Showing the first eight; more decompositions exist.
