Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585892, here are decompositions:

3 + 31585889 = 31585892
43 + 31585849 = 31585892
109 + 31585783 = 31585892
229 + 31585663 = 31585892
313 + 31585579 = 31585892
433 + 31585459 = 31585892
439 + 31585453 = 31585892
523 + 31585369 = 31585892

Showing the first eight; more decompositions exist.
