Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579084, here are decompositions:

11 + 31579073 = 31579084
137 + 31578947 = 31579084
197 + 31578887 = 31579084
263 + 31578821 = 31579084
293 + 31578791 = 31579084
347 + 31578737 = 31579084
353 + 31578731 = 31579084
461 + 31578623 = 31579084

Showing the first eight; more decompositions exist.
