Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579060, here are decompositions:

113 + 31578947 = 31579060
131 + 31578929 = 31579060
137 + 31578923 = 31579060
173 + 31578887 = 31579060
179 + 31578881 = 31579060
239 + 31578821 = 31579060
269 + 31578791 = 31579060
449 + 31578611 = 31579060

Showing the first eight; more decompositions exist.
